سورة الأعلى

Imam Sadiq (peace be upon him): The fast is completed by paying zakat al-fitrah, just as the prayer reaches its completion by sending blessings (salawat) upon the Messenger of Allah (peace be upon him and his family). So whoever fasts but deliberately omits zakat al-fitrah, there is no fast for him; and whoever prays but does not send blessings upon the Messenger of Allah (peace be upon him and his family) and deliberately omits it, there is no prayer for him. For Allah, the Mighty and Majestic, placed zakat al-fitrah before the prayer and said: قَدْ أَفْلَحَ مَن تَزَکَّی * وَ ذَکَرَ اسْمَ رَبِّهِ فَصَلَّی [He indeed shall be successful who purifies himself, and magnifies the name of his Lord and prays].

Imam Sadiq (peace be upon him): قَدْ أَفْلَحَ مَنْ تَزَکَّی [He indeed shall be successful who purifies himself] — what is meant is the one who takes out zakat al-fitrah from his wealth.

The Messenger of Allah (peace be upon him and his family): Abu Dharr (may Allah have mercy on him) said: I said, "O Messenger of Allah (peace be upon him and his family), is there anything in our hands, from what Allah has revealed upon you, of what was in the scriptures of Ibrahim and Musa (peace be upon them)?" He said: "O Abu Dharr (may Allah have mercy on him)! Recite: قَدْ أَفْلَحَ مَنْ تَزَکَّی* وَ ذَکَرَ اسْمَ رَبِّهِ فَصَلَّی* بَلْ تُؤْثِرُونَ الْحَیاةَ الدُّنْیا* وَ الْآخِرَةُ خَیْرٌ وَ أَبْقی* إِنَّ هذا لَفِی الصُّحُفِ الْأُولی* صُحُفِ إِبْراهِیمَ وَ مُوسی [Indeed, whoever sought purity (and purified himself) has attained success. And (the one who) remembered the name of his Lord and then prayed! But you prefer the life of this world, while the Hereafter is better and more lasting! Indeed these commands were (also) in the earlier heavenly scriptures, in the scriptures of Ibrahim and Musa]. (Al-A'la 14–19)."

The Messenger of Allah (peace be upon him and his family): Ibn Salam said: O Muhammad (peace be upon him and his family), is anything of these scriptures recorded in your book? He said: "Yes, O son of Salam." He asked: "What is it, O Muhammad (peace be upon him and his family)?" He said: The Prophet (peace be upon him and his family) recited to him: قَدْ أَفْلَحَ مَنْ تَزَکَّی* وَ ذَکَرَ اسْمَ رَبِّهِ فَصَلَّی* بَلْ تُؤْثِرُونَ الحَیاةَ الدُّنْیا* وَ الْآخِرَةُ خَیْرٌ وَ أَبْقی* إِنَّ هذا لَفِی الصُّحُفِ الْأُولی* صُحُفِ إِبْراهِیمَ وَ مُوسی [He indeed shall be successful who purifies himself, and magnifies the name of his Lord and prays. But you prefer the life of this world, while the Hereafter is better and more lasting. Indeed this is in the earlier scriptures, the scriptures of Ibrahim and Musa].
