Surah 22. Al-Hajj
Ayah 34 - 35
34 وَلِكُلِّ أُمَّةٍ جَعَلْنَا مَنسَكًا لِّيَذْكُرُوا۟ ٱسْمَ ٱللَّهِ عَلَىٰ مَا رَزَقَهُم مِّنۢ بَهِيمَةِ ٱلْأَنْعَـٰمِ ۗ فَإِلَـٰهُكُمْ إِلَـٰهٌ وَٰحِدٌ فَلَهُۥٓ أَسْلِمُوا۟ ۗ وَبَشِّرِ ٱلْمُخْبِتِينَ
35 ٱلَّذِينَ إِذَا ذُكِرَ ٱللَّهُ وَجِلَتْ قُلُوبُهُمْ وَٱلصَّـٰبِرِينَ عَلَىٰ مَآ أَصَابَهُمْ وَٱلْمُقِيمِى ٱلصَّلَوٰةِ وَمِمَّا رَزَقْنَـٰهُمْ يُنفِقُونَ
[34-35] For every community We have prescribed a way of sacrifice so that the people (of that community) should pronounce the name of Allah over the cattle which He has provided for them,64 (but one and the same object underlies all the different ways). So your Deity is One Deity: surrender to Him alone. And, O Prophet, give good news to those who adopt a humble way,65 whose hearts are filled with awe when Allah is mentioned before them: who endure with fortitude any affliction that befalls them: and who establish Salat and expend of what We have given them.66
64This verse implies two things:
(1) Sacrifice has been an essential part of the worship of One Allah in all the revealed religions. In order to inculcate Tauhid, Allah prohibited sacrifice for anyone other than Himself. This was in keeping with the other prohibitions which were made for others than Allah. For instance, "prostration" before anyone other than Allah, making vows for others than Allah, visiting holy places others than those prescribed by Allah, fasting in the name of others than of Alla, etc., were all prohibited.
(2) The other thing which has been common in all the revealed religions was the object of the sacrifice in the name of Allah though its details have been different in different religions, times and countries.
65The Arabic word `mukhbitin' has no equivalent in English. It includes those who (1) give up pride, arrogance and adopt humility before Allah, (2) surrender themselves to His service and slavery, and (3) accept His decrees sincerely.
66It means that righteous people spend their lawful provisions in the Way of Allah to meet their own and their dependents' lawful needs, to help their relatives, neighbors and other needy people, on public works and propagation of the Word of Allah. It does not include expenditure in unlawful ways for unlawful purposes. The Qur'anic term lnfaq implies neither over-spending nor being miserly and stingy, but spending one's wealth on oneself and others according to one's means and status in society.
