سورة ابراهيم

Ibn Abbas (may Allah have mercy on him): O Muhammad (peace be upon him and his family)! قُلْ لِعِبَادِیَ الَّذِینَ آمَنُوا [Say to My servants who have believed]; that is, to the servants who have acknowledged the oneness of Allah and His justice. What is meant is the companions of the Prophet (peace be upon him and his family).

Imam Sadiq (peace be upon him): Allah the Exalted has made obligatory upon the wealthy, in their properties, rights for the poor other than zakat, and He, the Mighty and Majestic, said: "And those in whose wealth is a known right" (al-Ma'arij/24). So the known right in the verse is something other than zakat; that is, something a person makes obligatory upon himself in his wealth. He must impose it upon himself in accordance with his capacity and the extent of his wealth. Then he pays the amount he has made obligatory upon himself — every day, or if he wishes every Friday, or every month. Allah the Exalted has also said: "And those who [in this way] give Allah a goodly loan" (al-Hadid/18) — and this is other than zakat. Allah the Exalted has also said: یُنْفِقُوا مِمَّا رَزَقْناهُمْ سِرًّا وَ عَلانِیَةً [that they should spend of what We have provided them, secretly and openly].

Ali ibn Ibrahim (may Allah have mercy on him): یَوْمٌ لاَّ بَیْعٌ فِیهِ وَ لاَ خِلاَلٌ [a day in which there is no bartering nor mutual befriending] — meaning there is no friendship at work.
