A British ISIS fighter has complained about fellow jihadis fleeing the frontline then boasting of their bravery on Twitter while posing with their weapons. Omar Hussain, 27, from High Wycombe, regularly makes videos and posts on social media about life in the so-called Islamic State under the name Abu Sa'eed Al-Britani. Last month he complained about peeling potatoes and his troubles with washing his clothes. In his latest video the former Morrisons security guard, who used to live at home with his mother and has not managed to get himself a jihadi bride, accuses a fellow 'brother' of running away from the frontline in Syria 'When it was only him and me defending the post'. Omar Hussain, 27, from High Wycombe, posts videos online under the name Abu Sa'eed Al-Britani. He has complained about jihadis who leave their posts then boasting on social media about their bravery . Islamic State fighters pose at the border between Syria and Iraq. Hussain has cautioned 'sisters' to choose wisely when searching for a spouse among ISIS fighters . A jihadi poses with a handgun and an ISIS ring in a social media post. Hussain has warned would-be jihadi brides to be wary of fighters who seem to spend too much time online . He said: 'I can recall myself shouting at him to come back as he ran away leaving me alone to defend the position. 'The ironical thing here was that the brother went online the next day and praised how Dawlah [Islamic State] managed to defend an onslaught by the enemy, and how people in the west need to "stop being cowards". 'On other occasions, I have noticed how some brothers praise how "we" attacked such and such village, how hard the battle was for "us", etc. yet they were not there. 'A form of tadlees (twisting the haqq [truth] to get self praise), not a characteristic stemming from humbleness and sincerity.' Hussain, who has previously issued advice on how jihadists should 'deal' with wannabe jihadi brides, has now cautioned 'sisters' to choose wisely when searching for a spouse among ISIS fighters. He said: 'Although there may be nothing wrong with marrying a brother who is constantly online, I would just like to say that its best one does not rush into a marriage contract. 'I have been in Sham [the Caliphate] for just over a year now and I have seen many beautiful brothers who are constant on their ibaadah [worship], warriors in front lines, have amazing military minds, generous towards others, humble, funny, etc. yet are unknown on social media. 'So sisters, please be careful and deliberate when choosing a spouse. We are still human beings, we err and we make mistakes. 'Some people's intentions can sidetrack, especially when on social media platforms.' A jihadi poses with an AK-47 and a handgun. Some fighters boast online about how 'we' attacked a village when they weren't even part of any ISIS assault, according to Hussein . Despite his hatred of the West this ISIS fighter enjoys showing off his Adidas trainers in this online post . Hussain himself poses with an AK-47 in Raqqa, Syria. He often posts videos containing his opinions on life inside the so-called Islamic State . The British jihadi decries boastful fellow fighters who are 'always on twitter posting pics of [themselves]' rather than actually fighting on the frontline - which should make would-be wives wary given electronic devices are banned there. He adds: 'The only reason a brother can be constantly on twitter, fb, Instagram or other social media platform, is if he's not on front lines.' Hussain continues that all ISIS members in the area controlled by the group have guns and not just the fighters. 'Just because someone is in Sham and has a gun, it does not mean they are a Mujaahid,' he says. 'Immaturity makes a person over excited. And being over excited leads to posting pics online with a gun. 'Do not be afraid to reject a proposal, there are many brothers here in Sham. And some of the most beautiful are those who are always on ribat [the frontline] and completely unknown on social media platforms.' And in a missive posted yesterday Hussain railed against jihadis who moan 'like menstruating women' about the guns they've been given. Jihadists based in Atmeh - just one mile from the Olive Tree refugee camp in Syria - have boasted of living 'the goodly life' in a huge hilltop villa - a far cry from the frontline in the country's brutal civil war . Bethnal Green teenagers Kadiza Sultana, Shamima Begum and Amira Abase all ran away from their homes apparently to be jihadi brides. Hussain says such girls should chose their husbands carefully . It is feared the three are now married to ISIS fighters. Hussain has complained at how some moan like 'menstruating women' at the guns they have been given . Hussain admits on Twitter that it took him 50 minutes to peel 10 potatoes - leaving him too tired to cut them . He says to his 'beloved brothers in Islam': 'Know that yesterday you had nothing of honor in your hands and were subjugated under the laws of the Kuffar [unbeliever] . 'You carried no bullets, no gun, no grenade, nothing of this sort. Yet here you are today with honor given to you, so do not boast about what you have been given. 'For you have been given it due to the sacrifices of your brothers before you…The soldiers who fought the battles while you were sitting at home. 'Likewise, do not complain when you are given a gun which you do not like… What were you walking around with last month? In Dar Al-Kufr [any non-Muslim country], did you have a brand new Russian AK47? 'Did you have a Glock? You didn’t even have a rusty old gun, yet here you are complaining like a menstruating woman about the very find details of your gun!' Yet Hussain has form when it comes to spending a time posting on social media rather than taking the fight to ISIS' Syrian government or Kurdish enemies or dodging US airstrikes - and he's not averse to sharing pictures of himself brandishing an AK-47 either. Earlier this month he complained on Twitter about his difficulties completing the most basic daily jobs including peeling potatoes for his dinner and washing his clothes. In August Last August he appeared on BBC2's Newsnight, saying: 'I hate the UK, the only reason why I would intend to return to the UK is when I want to come and plant a bomb somewhere.'
