Thus, there is much importance and excellence of offering Salaat in the night, even though a short one that takes only some time. To exhort us to do so, the Holy Prophet (Sallallahu alaihi wa sallam) has given us sinners such leniency that even if one offers Salaat after Salaat Ul ‘Isha, that person will be granted the blessings of night worship. As mentioned in this Hadith:
It is narrated on the authority of Hadhrat Ayaas bin Mu’awiya Mizni (May Allah be well pleased with him) that the Holy Prophet (Sallallahu alaihi wa sallam) said: Be it for the time taken to milk a goat, but do offer Salaat in the night. The supererogatory (Nafl) offered after Salaat Ul ‘Isha is also included in this. (Mo’jam Kabeer Tabarani, Hadith No. 785; At Targheeb Wat Tarheeb, Vol. 1, Pg. No. 431)
