Al-Hasib (The Reckoner, The Sufficient) in the Holy Quran

﴿وَٱبۡتَلُواْ ٱلۡيَتَٰمَىٰ حَتَّىٰٓ إِذَا بَلَغُواْ ٱلنِّكَاحَ فَإِنۡ ءَانَسۡتُم مِّنۡهُمۡ رُشۡدٗا فَٱدۡفَعُوٓاْ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡۖ وَلَا تَأۡكُلُوهَآ إِسۡرَافٗا وَبِدَارًا أَن يَكۡبَرُواْۚ وَمَن كَانَ غَنِيّٗا فَلۡيَسۡتَعۡفِفۡۖ وَمَن كَانَ فَقِيرٗا فَلۡيَأۡكُلۡ بِٱلۡمَعۡرُوفِۚ فَإِذَا دَفَعۡتُمۡ إِلَيۡهِمۡ أَمۡوَٰلَهُمۡ فَأَشۡهِدُواْ عَلَيۡهِمۡۚ وَكَفَىٰ بِٱللَّهِ حَسِيبٗا ﴾ [An-Nisā’: 6]

(6) And test the orphans [in their abilities] until they reach marriageable age. Then if you perceive in them sound judgement, release their property to them. And do not consume it excessively and quickly, [anticipating] that they will grow up. And whoever, [when acting as guardian], is self-sufficient should refrain [from taking a fee]; and whoever is poor - let him take according to what is acceptable. Then when you release their property to them, bring witnesses upon them. And sufficient is Allah as Accountant.

Surah: An-Nisā’ - Verse: 6 - Juz: 4 - Page: 77

﴿ٱللَّهُ لَآ إِلَٰهَ إِلَّا هُوَۚ لَيَجۡمَعَنَّكُمۡ إِلَىٰ يَوۡمِ ٱلۡقِيَٰمَةِ لَا رَيۡبَ فِيهِۗ وَمَنۡ أَصۡدَقُ مِنَ ٱللَّهِ حَدِيثٗا ﴾ [An-Nisā’: 87]

(87) Allah - there is no deity except Him. He will surely assemble you for [account on] the Day of Resurrection, about which there is no doubt. And who is more truthful than Allah in statement.

Surah: An-Nisā’ - Verse: 87 - Juz: 5 - Page: 92

﴿ٱلَّذِينَ يُبَلِّغُونَ رِسَٰلَٰتِ ٱللَّهِ وَيَخۡشَوۡنَهُۥ وَلَا يَخۡشَوۡنَ أَحَدًا إِلَّا ٱللَّهَۗ وَكَفَىٰ بِٱللَّهِ حَسِيبٗا ﴾ [Al-Aḥzāb: 39]

(39) [Allah praises] those who convey the messages of Allah and fear Him and do not fear anyone but Allah. And sufficient is Allah as Accountant.
