Abbas' son tells of the time when a Bedouin came to the Messenger of Allah and asked, "How can I be sure that you are a Prophet?" The Messenger of Allah said, "If I call upon that branch of this tree to obey me, will you bear witness that I am the Messenger of Allah?" Then, the Messenger of Allah called to the branch to come down, and it started to come down and then fell before the Prophet and thereafter returned to its place (after bearing witness), whereupon the Bedouin became Muslim.
Ina Abbas 'sheegayaa waqtiga marka Baadiyaha ah in Rasuulka Alle yimid oo ku yidhi, "Sidee baan u hubsan kartaa inaad nebi tahay?" Rasuulka Alle yiri, "Haddii aan ku dul laan in geed this wac si aad i adeeca, bay kuu dhali doontaa marag inaan anigu ahay Rasuulkii Eebe ahaa?" Markaas, Rasuulka Alle loo yaqaaninay isku laan ku soo degin, oo waxa ay bilowday in ay u soo degay oo markaas ka hor Nabiga ku dhacay oo intaas ka dib ku soo laabtay ay meel (ka dib markii ay u markhaati furayso), oo korkoodana waxaa Baadiyaha u noqday Muslim.
