ٱللَّهُ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ مِنْ عِبَادِهِۦ وَيَقْدِرُ لَهُۥٓ ۚ إِنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ Qur’an Al-Ankabut (29:62)Allahu yabsutu alrrizqa liman yashao min AAibadihi wayaqdiru lahu inna Allaha bikulli shayin AAaleemun
Sc., "and, hence, knows what is really good and, from the viewpoint of His unfathomable plan, necessary for each living being".
Cf. xiii. 26. Unequal gifts are not a sign of chaos in Allah's universe. Allah provides for all according to their real needs and their most suitable requirements, according to His perfect knowledge and understanding of His creatures.
