Imam al-Awza'i (may Allah have mercy on him) said: We leave five things of the people of Iraq: (1) drinking intoxicants, (2) eating at the time of Fajr in Ramadan, (3) Friday prayer being held only in seven cities, (4) delaying the Asr prayer until the shadow becomes four times (the length of the object), and (5) fleeing from battle.
Of the views of the people of the Hijaz: (1) combining prayers without an excuse, (2) temporary marriage (mut'ah) with women, (3) one dirham for two dirhams, and one dinar for two dinars, hand to hand, (4) approaching women in their rear, and (5) listening to amusements.
