Asslm dear mufti/molvi. My question is regarding intermingling of men and women at occasions such as marriages. Mufti meerun sahib has always strictly prohibited it. During his living not all molvis of JUM followed it. I've seen some molvis attend gatherings with men and women. They used to sit and eat food on tables with ghair mahram. They still do it. 1. What is JUM's stand regarding their own molvis that dont follow their rules? 2. Should these kinds of molvis be put forward for leading salaat in mosques where they are not imam while the actual imam and other molvis are present? Jazaakumullahu khayran.

The imam doesn't make dua after namaz. He just sits and makes his own tasbeeh and stands up after few mins after making salaam. Sometimes after making his tasbeeh he raises his hands and makes his own silent dua 2 3 mins after namaz has ended. This is rare also. Is this correct?

aslmkm if in a jahri salaah the imam mistakenly read sofly but then he realized just after few verses of surah fatihah. now should he start surah fatihah again or he should continue? and should he make sajdah sahw?

Ene personne pas ressi fer namaz en jamaat lakoz travay, li fer li individuellement. Eski li 1 peche?
