Rasulullah’s Weeping The Whole Night

Story of the Rasulullah’s Weeping The Whole Night

Once Rasulullah (sallallahu alaihi wasallam) kept weeping the whole night through, repeating again and again the following ayah.
If Thou punish them, they are Thy slaves, and if Thou forgive them, Thou only art the Mighty, the Wise (al-ma’idah 118)

It is said about Iman Abu Hanifah (rahmatullah alaihi) that he also once wept the whole night, reciting the following ayah of the Quran in tahajjud: 

     But avaunt ye, O ye guilty, this day (yasin 59)
This ayah means that on the day of qiyamah the guilty will be asked to separate themselves from the good people, and will not be allowed to mix with them as they were doing in the worldly life. Why should not the people with fear of Allah ta’ala in their weep in anxiety regarding which class they will belong to on that day?
