It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Soon there will be men in my Ummah who will eat all kinds of food, drink all kinds of drinks and wear all kinds of clothes, and who will speak affectedly with wide-open mouths (showing off in their speech). These are the worst people of my Ummah."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu Bakr except Muhammad bin Himyar."
