HADITH: It is narrated by Abu Hurayrah (RadiyAllahu Anhu) that the Messenger of Allah (SallAllahu Alayhi Wa Sallam) said:
“0 people! Allah is Pure Himself, and accepts only what is pure, and He has given the same Command, concerning it, to all Believers as He has to His Prophets (AS).
For them, the Commandment is:
“0 ye Messengers! Eat of the good (and lawful) things, and do right.”
(Al Mu’minoon 23:51)
And for the Believers:
“O Mankind! Eat of what is lawful and wholesome in the earth (and avoid what is impure).”
(Al Baqarah 2:172)
After it, Abu Hurairah (RA) said: The Messenger of Allah (SAWS) narrated the story of a man who undertook a long journey (to a holy place) and arrived (there) in such a condition that his hair were disheveled and his body was covered with dust. He raised his hands towards the heaven and cried: “O Lord! O my Preserver!”
But his food was impure, his dress was impure and he had been brought up with what was impure. How his prayer can, then, be granted?”
[Muslim]
Commentary:
The gist of above tradition is that Allah (SWT) is Pure and accepts only offerings that are pure, i.e., from goods acquired through legitimate means. It further denotes that the commandment to eat the good and lawful things was given to all the Prophets (A.S.) in the same way as given to all the Believers. A true Believer should, therefore, realize the significance of the Divine commandment and observe it scrupulously. The Holy Prophet (SAWS) has, also, emphasized that ill-gotten wealth is so hateful to Allah (SWT) that even if a man went to a Sacred place, like a miserable beggar, to supplicate to the Almighty, but his food and clothes were impure, hence his supplication would not be accepted.
