i have a few questions to be answered:
1) can the Jumu'ah Khutbah be shortened due to weather conditions? eg: temperature is above 40 degree celsius and more than half of musallees are outside the masjid because no place to accomodate them inside.
2) can the Imam lengthen his ruku to enable someone who entered masjid to join so that he doesnt lose his rakah?
3) can the Imam lengthen while in tashahhud to enable someone who entered masjid to join so that he doesnt lose his salah?
4) during khutbah it is not allowed to speak or even recite durood: a) in the break between the 2 khutbahs can one make dua? b) when Imam starts making dua at end of khutbah, can we say Ameen?
