Third Hadith (Allah is Pure)
Abu Hurairah (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "O people! Allah is Pure and, therefore, accepts only that which is pure. Allah has commanded the believers as He has commanded His Messengers by saying: '[Allah said],"O messengers, eat from the good foods and work righteousness. Indeed, I, of what you do, am Knowing.' (23:51) And He said: 'O you who have believed, eat from the good things which We have provided for you...' (2:172). Then he (ﷺ) made a mention of the person who travels for a long period of time, his hair are disheveled and covered with dust. He lifts his hand towards the sky and thus makes the supplication: 'My Rubb! My Rubb!' But his food is unlawful, his drink is unlawful, his clothes are unlawful and his nourishment is unlawful, how can, then his supplication be accepted?” [Muslim].
