When ‘Othman ibn ‘Affan became caliph, following the death of ‘’Umar (23 - 35 A.H./644 - 656 A.D.), he granted Fadak to Marwan ibn al-Hakam, his cousin (see Al-Sunan al-Kubra, Vol. 6, p. 301; Wafa' al-Wafa', Vol. 3, p. 1000; Ibn Abul-Hadid, Vol. 1, p. 198) and this was one of the causes of hostile feelings among the Muslims against ‘Othman: Refer to Al-Ma’arif, Ibn Qutaybah, p. 195; Al-’Iqd al-Farid, Vol. 4, pp. 283, 435; Abul-Fida', Tarikh,Vol. 1, p. 168; Ibn al-Wardi, Tarikh, Vol. 1, p. 204.

Al Imam Ja'afer as-Sadiq a.s. ameripoti riwayah kutoka kwa Mtume Muhammad Mustafa s.a.w.w. ambaye ameseama: "kwa baraka za Sadaka Allah swt humwondolea mwenye kutoa Sadaka balaa sabini, ambamo kuna magonjwa, madhara yatokanayo na moto, kuzama maji, kufunikwa na majumba mpaka kufa na atamwepusha ili asiwehuke au asiwe mwehu." 581. Al Imam Ja'afer as-Sadiq a.s. ameripoti riwayah kutoka Al Imam 'Ali ibn Abi Talib a.s. kuwa: "Ili kutaka kuepukana na shari za madhalimu basi toeni Sadaka."
