Salaah

Musallees making sajdah on the step of the mimbar

Q: In order to create more space in the Musjid for Musallees on the occasion of Jumuah, we ask all the Musallees to move forward one step. The problem is that those Musallees in the first saff who are in line with the Mimbar, when they step forward, they have insufficient space for sajdah and thus make make sajdah on the step of the mimbar.

1.Is the Salaah of these Musallees valid?

2.If the Salaah is valid, is it Makrooh for them to make Sajdah in this manner?

3.In these circumstances, is it permissible to leave a gap in the first saff in line with the mimbar?

Forgetting to recite a Surah in the third rakaat of Sunnat Salaah

Q: I performed the four sunnah of Asr salaah however in the 3rd rakaat I forgot to read a Surah after Surah Fatiha only realised this in ruku. I intended to make sajda sahwa but after the 4th rakaat I read the tashahud, durood and dua and made both salaams. Whilst making the second salaam I remembered the sajda-e-sahw and immediately made a sajda after then completed the Salaah. Was I correct or did I have to repeat the Salaah?

Forgoing Salaah

Q: I want to ask that I am a university student and often it happens to me that I miss prayer due to classes. So I want to ask that how I can I perform my prayers after the time of that particular prayer has ended?

Tahajjud Salaah

Q: I want to know is it compulsory to sleep before performing tahujjud Salaah? If a person is awake till 3 am, can he/she then perform the Salaah? I have heard from many people that it's necessary to sleep before.
