Assalamualaikum Wa Rahmatullahi Wa Barakatuh i want to know about praying of daily sunnah prayer which is 12 a day. I heard from Aalim that we can pray this 12 sunnah prayer before sleeping after ishan prayer. Is this correct? or if we left before zohar sunnah prayers can we pray after zohar farz? please advice me from Quran & Sunnah Insha Allah

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

The confirmed optional prayers have a specified time when they should be performed. For instance, the optional prayer of the Thuhr prayer is 6 supererogatory prayers: 4 before the Thuhr obligatory prayer and 2 after it, and in principle these prayers should be performed at the time of the Thuhr prayer. Also, the optional prayer of Maghrib should be performed at its time. The same thing applies to optional prayers which should be performed along with the prayer which is related to it.

Therefore, a Muslim should perform each optional prayer at its specified time as the Prophet performed these prayers at their specified time.

However, if a person is preoccupied from performing them or from performing some of them, it is permissible for him to make them up anytime during the day or night, either after or before ‘Ishaa’ prayer; indeed this is the most preponderant opinion, and this is the well-known view of the Shaafi'i School.
