Kutoka kwa Abu Hurairah (Radhi za Allah ziwe juu yake) amesema: Mjumbe wa Allah amesema: "Hakika Allah Ta'ala ni Mwema na hakubali isipokuwa kilicho kizuri. Na Allah amewaamrisha waumini yale aliyowaamrisha Mitume... Kisha akamtaja mtu anayesafiri safari ndefu, akiwa amenyauka na mwenye vumbi, akinyoosha mikono yake kuelekea mbinguni akiomba: Ee Mola wangu! Ee Mola wangu! Hali ya kuwa chakula chake ni haramu, kinywaji chake ni haramu, vazi lake ni haramu, na amelishwa kwa haramu; basi atawezaje kujibiwa dua yake?!"

On the authority of Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah said: "Allah the Almighty is Pure and accepts only that which is pure. And Allah has commanded the believers what He has commanded the Messengers... Then he mentioned a man who, having journeyed far, is disheveled and dusty, and who spreads out his hands to the sky saying 'O Lord! O Lord!' while his food is unlawful, his drink is unlawful, his clothing is unlawful, and he has been nourished with what is unlawful; so how can his supplication be answered?!"
