Q 1: I usually
offer the obligatory Salah (Prayer) such as Zhuhr (Noon) Prayer at the Masjid (mosque). After I go home, I offer the Sunnah prayer. Sometimes, I offer the Sunnah prayer one or two hours after the obligatory Salah.
What is the ruling on doing this?
If the situation is as you have mentioned, then there is no harm if you offer it before the elapse of its due time. However, it is better to offer the Nafilah (supererogatory) Salah as soon as possible lest you should miss it due to work or forgetfulness or the like.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
