Q 1: My
neighbor does not offer Salah (Prayer)
although we have repeatedly advised him. What should I do? What is the ruling of Islam on this matter? My other neighbor does not offer Salah in the Masjid (mosque) out of laziness.
You should cooperate with other Muslims to advise him gently. In case he does not respond to you, abandon him. The same should be done with the person who neglects offering congregational Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
