Allaah said:
مَن كَانَ يُرِيدُ حَرْثَ الْآخِرَةِ نَزِدْ لَهُ فِي حَرْثِهِ ۖ وَمَن كَانَ يُرِيدُ حَرْثَ الدُّنْيَا نُؤْتِهِ مِنْهَا وَمَا لَهُ فِي الْآخِرَةِ مِن نَّصِيبٍ
“Whosoever
desires (by his deeds) the reward of the
Hereafter, We give him increase in his reward, and whosoever desires the reward
of this world (by his deeds), We give him thereof (what is decreed for him),
and he has no portion in the Hereafter.
