Surah 76 (Al‑Dah'r), Ayahs 5‑22 honor Ahlul Bayt's quality.
إِنَّ الاَبْرَارَ يَشْرَبُونَ مِن كَأْسٍ كَانَ مِزَاجُهَا كَافُورًا
عَيْنًا يَشْرَبُ بِهَا عِبَادُ اللَّهِ يُفَجِّرُونَهَا تَفْجِيرًا
يُوفُونَ بِالنَّذْرِ وَيَخَافُونَ يَوْمًا كَانَ شَرُّهُ مُسْتَطِيرًا
وَيُطْعِمُونَ الطَّعَامَ عَلَى حُبِّهِ مِسْكِينًا وَيَتِيمًا وَأَسِيرًا
Verily the Righteous [about Ahlul Bayt] shall drink from a cup tempered with Kafoor; from a well‑spring the servants of Allah shall drink, flowing in abundance;
they fulfill their vows, and fear the Day whose evil shall spread far and wide;
And (in spite of their need), they give food to the poor, the orphans, and the captives, out of love for Allah, ....
The Occasion
It was not the month of Ramadhan but Ali and Fatima were fasting (Fast of Vowالنذر ). They were at home and Fatima (a.s.) was preparing the food to break the fast.
As Ali and Fatima sat to break their fast they heard a knock on the door. They saw a man in ragged clothes standing, his hands shaking, and his face pale. He asked if he could be helped and fed. The man was invited in and offered the food available. The man took the food, thanked them, and then left. Both Ali and Fatima were left with nothing to eat and little to cook for Suhoor.
Ali and Fatima fasted the following day, and when time for breaking the fast was due, once more a knock on the door was heard. This time someone claiming to be an orphan was asking for help. He too was offered the available food, and with thanks, he took the food then left.
On the third day, both Ali and Fatima were once again fasting, and when time for breaking the fast was due they were weak, shaky, and dizzy for lack of nourishment, even difficult to hold themselves steady. Once more at this time a knock was heard! This time a destitute man was in need of food. Ali and Fatima couldn't help but again offer him their food. Thus Ali and Fatima underwent three days of fasting, hardly having anything to eat. This was done as a duty, since this was for the love of the Almighty; they would rather help the others than themselves.
For this occasion a remarkable Revelation [of 18 verses] was sent down to Muhammad in honor of these two, Fatima and Ali. The Revelation specified them in terms of: Out of love for Allah, they feed the poor, the orphan, and the destitute. And the revelations continued to describe their lofty station with Allah —in the Garden of Bliss [Paradise].[8] It described a world tantalizing with delights and enchanting existence waiting for their arrival, for Allah has so rewarded them for their earnestness in His service, dedication to His cause, and their intense love for Him.
