It is best to pray at the masjid as this is the way of the Prophet salla Allahu alaihi wa sallam in Ramadan.

And Allah knows best

During qayam al Lail since many of the non Arabic speakers do not understand what the Imam is supplicating, is it better to pray at Masjid in congregation or can one pray at home and supplicate to Allah Subhana Wa Taala one to one.

I hear the Adhaan of several Masjids but the Masjid that I go gives Adhaan 2-3 minutes later to all the Masjids. I usually go before the Adhaan to the Masjid I attend so if I reach the Masjid before the Fajr Adhaan can I pray the Sunnah as I heard the other Masjid’s Adhaan? or I should wait for the Masjid which I attend to give Adhaan then proceed.

In my country (India)there are a lot of masajid attached to graves of saints, and in some masajids ther are graves. Sometimes its hard to identify and at time of salat can we offer prayers in them if we do not know they have graves in it.And i knew a masajid which has a grave inside its boundry but my friend sometimes insists praying in it how can I deny to him that i cannot offer my prayer with him.
