Q: I am living in Canada and perform salaah in a masjid or musalla where sometimes the salah is led by an Imam whose pants are below his ankle or someone has no beard and I don’t have any other choice. This happened once in a while. Do I have to repeat that salah after the jamaat or will it be okay? If I have to repeat the salah then I can repeat it in the future if this one happens but what about the past salah that I don’t know how many it was.

Q: If a Hanafi performs salaah behind a shaafi imaam, and the shaafi imaam recites the aayat of sajdah on the last page of surah hajj (which is an aayat of sajdah according to the shaafis and not the hanafis), then the shaafi imaam goes into sajdah and the Hanafi muqtadi follows him in sajdah, then what is the status of the hanafi muqtadi’s salaah? Is his salaah valid or does he have to repeat his salaah?

Q: If in congregational prayers and Jumu'ah and Eidain, the Imam is in the indoor hall of the masjid and saffs are made behind him and the door of the hall is closed but not locked and saffs are also made outside, but there is a distance of 3 saffs between the last indoor saff and the first outdoor saff, are the congregational prayers or Jumu'ah or Eidain prayers valid?

Q: In a small Masjid, the Imam used a sutrah while leading the jamaat (it is a common practice in some places to do second or third jamaat if the main jamaat is missed). Is it permissible to pass in front of people who missed their rakaat with the Imam in these second/third jamaat are completing their prayers. Will they still be considered to be behind sutrah even if Imam has completed his own Prayer?

Q: Is it necessary for the imaam to make intention for the people behind him? Example if there's women in the jamaat, does he have to specify he's leading the salaah for women?
