Salaah

Sajda-e-sahw in a makrooh time

Q: I read that if after the salaam of the salaat a makruh time enters and there was a sajdah sahw to be made, then one is absolved from doing sajdah sahw. But he must repeat the whole salaah. For example, if after the salaam in Fajr the sun has risen, then one should not do sajdah sahw, but he must repeat the whole salaah later on. The same counts for Asr when after the salaah the makruh time enters (i.e. after the suns rays become yellow/orange meaning when one is able to look at the sun without being dazzeld). Is this true ? The same ruling would apply to someone who forgot the sajdah sahw, or lost wudhu after salaam before the sajdah sahw.

Qadha Salaah after fajr and after asr

Q:

  1. Can Qadha salaah (esp. Qadha Umri) be performed after the fardh of fajr and asr? If so then what salaah are not permitted at that time?
  2. On safar, a person does not perform a salaah e.g. asr. On returning home from the journey, does one perform qasr (i.e. 2 rakaats qadah) or 4 rakaats of qadah?
  3. Likewise, if a person omits a salaah e.g. asr in his hometown, whilst on safar does the person perform 4 rakaats of qadah or 2  rakaats of qadah for the salaah missed whilst still at home?
