وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦ وَٱلْأَرْضُ جَمِيعًۭا قَبْضَتُهُۥ يَوْمَ ٱلْقِيَٰمَةِ وَٱلسَّمَٰوَٰتُ مَطْوِيَّٰتٌۢ بِيَمِينِهِۦ ۚ سُبْحَٰنَهُۥ وَتَعَٰلَىٰ عَمَّا يُشْرِكُونَ
And they esteem not Allah as He hath the right to be esteemed, when the whole earth is His handful on the Day of Resurrection, and the heavens are rolled in His right hand. Glorified is He and High Exalted from all that they ascribe as partner (unto Him).

Chapter: The one whom Allah gives something without his asking for it
Narrated `Umar:
Allah's Messenger (ﷺ) used to give me something but I would say to him, "would you give it to a poorer and more needy one than l?" The Prophet (p.b.u.h) said to me, "Take it. If you are given something from this property, without asking for it or having greed for it take it; and if not given, do not run for it."
Sahih al-Bukhari 1473
