Hadith on Tawhid: Allah’s dominion not decreased by spending

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “The hand of Allah is full and it is not diminished by continuous spending night and day. Do you not see that He has been spending since the creation of the heavens and the earth, and it has not decreased anything in His hand?

عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ يَدُ اللَّهِ مَلْأَى لَا يَغِيضُهَا نَفَقَةٌ سَحَّاءُ اللَّيْلَ وَالنَّهَارَ أَرَأَيْتُمْ مَا أَنْفَقَ مُنْذُ خَلَقَ السَّمَوَاتِ وَالْأَرْضَ فَإِنَّهُ لَمْ يَغِضْ مَا فِي يَدِهِ
