Nouman Ali Khan delves into an explicit explanation for the Dua for the Ummah.
Abu Hurairah RA that the Messenger of Allah ﷺ said: "Verily Allah the Exalted is pure. He does not accept but that which is pure. Allah commands the believers with what He commanded the Messengers. Allah the Almighty has said: "O you Messengers! Eat of the good things and act righteously" [23:51-53]. And Allah the Almighty also said: "O you who believe! Eat of the good things that We have provided you with" [2:167-172]. Then he (the Prophet) mentioned (the case of) the man who, having journeyed far, is disheveled and dusty and who stretches out his hands to the sky (saying): "O Lord! O Lord!" (while) his food was unlawful, his drink was unlawful, his clothing was unlawful, and he is nourished with unlawful things, so how can he be answered?"
This Hadith has very profound meanings. Firstly, Allah has all the attributes of perfection and completeness, free from any kind of shortcomings, weaknesses or needs. Allah commanded the Believers (Mu'minin) in an identical manner as He commanded the Messengers. Another point to be extracted from this Hadith is that Sadaqah is only accepted by Allah if it is from Halal sources. This is based on the principle that "Allah is pure and only accepts what is pure".
If we adhere to these points, In Sha Allah, it will lead us to be better Muslims with a profound level of Iman. Then our deeds will be described as 'at-tayyib'. We will then be the 'tayyibun', that is, pure and blessed by Allah.
