Ma'arif al-Qur'an
Mufti Muhammad Shafi(2) Verses 268-269: وَمَا يَذَّكَّرُ إِلَّا أُولُو الْأَلْبَابِ الشَّيْطَانُ يَعِدُكُمُ الْفَقْرَ (الٰی قولہ): "Satan frightens you of poverty ... and only the men of understanding do observe the advice."When a person is obsessed with the idea that spending in charity will cause him poverty, when he does not pick up the courage to go ahead and spend - even after hearing the warning of Allah Almighty - and continues feeling that he should not spend out of what he has, and when, turning away from the Divine promise, his mind takes him to rely on the promise of Satan, he should better be sure that this apprehension of his is being generated by Satan. He should never say that he has never seen Satan, so how could he take orders from him? Conversely, should he come to think that not only his sins will be forgiven by spending in charities, but also his wealth will be blessed with increase - he should then be sure that this thought has come from Allah for which he should be grateful to Him. Allah's treasure never runs short.
He knows fully well - the open, the hidden, the intentions, the deeds - everything about everyone.
