Question: I am married to a very good man who treats me well, and together we have three children. However, he does not pray in the masjid, but regularly prays at home – whether or not he is busy. I do encourage him to [go and] pray in congregation in the masjid – and sometimes he relents [and goes], but most of the time he does not pay any heed [to my gentle reminders], and continues to regularly pray at home. [This being the case], what am I [now] obliged to do?
Response: Other than what she has [already] done, there is nothing more this woman is required to do other than to advise. It is befitting that she [continue to gently] repeat this advice to him in a manner which does not cause annoyance, bearing in mind his right over her that she extend advice to him.
 In a hadeeth transmitted by Muslim, no.2162 – the Messenger of Allaah ﷺ said:
«The rights of one Muslim over another are six»
It was said: ‘What are they, O Messenger of Allaah?’ He said:
«If you meet him, greet him with salaam; if he invites you, accept the invitation; if he asks for advice, give him sincere advice; if he sneezes and praises Allaah, say يَرْحَمُكَ اللَّهُ (may Allaah have mercy on you); if he falls sick, visit him; and if he dies, attend his funeral»
