Summarized Fatawaa
• Is it permissible to offer Tahajjud prayer after Witr prayer ?
It is permissible to offer voluntary prayer after Witr(an odd number prayer performed between Isha`a and Fajr) prayer. However, it is desirable that the night prayer be ended with Witr. Therefore, it is desirable for one, who thought that he was most probably going to wake up at night in order to offer Tahajjud, to offer Witr after it, but one, who fears that he might not wake up, should offer Witr before going to bed.
• What is the ruling on someone who doesn`t perform prayer?
Not performing prayer is a major sin, and one who doesn`t pray out of laziness is considered an oft-sinner ;whereas, the one who denies that it is mandatory is considered a disbeliever.
• Should I pick up the newspapers thrown at the street because they definitely contain sacred names?
Praise be to Allah the Lord of the Worlds.
The Messenger of Allah (PBUH) says, "Be mindful of Allah and He will protect you." Part of this is protecting whatever contains the name of Allah. Therefore, if you see a paper containing Allah's name thrown in the street, then you should grab it and similar papers, then burn them in a clean place. Doing so is permissible because Othman (May Allah be pleased with him) has burnt copies of the Quran which didn`t match the main Mus-haf. However, you aren`t required to collect every paper in the street. And Allah the Almighty knows best.
• Is it permissible to offer Istikhara prayer (seeking guidance) after Witr Prayer(A confirmed Sunnah which is offered after Isha prayer and before Fajir prayer with a minimum of 3 Rak`as and a maximum of 11)?
It is permissible to offer Istikhara before and after Witr prayer as it is permissible at any time except that in which prayer is disliked.
