Forbidden Times Of Salaah

It is not permissible to perform any Salaat whatsoever at the following times:
(a) At Sunrise;
(b) At Midday (Zawaal)
(c) At Sunset.
Salaat could be performed about 15 minutes after sunrise; five minutes after midday and immediately after sunset.
(d) Before sunset when the suns rays lose their heat and become yellowish.
No Salaat can be performed during this time excepting the Asr Salaat of that day if it has not yet been performed.  NB. It is not permissible to delay the performance of Asr Salaat until this time. However, if Asr Salaat was not yet performed then it has to be performed even in this Makrooh (reprehensible) time.
(e) When the Imam is delivering the Friday or Eid Khutba.

It is not permissible to perform any Sunnat or Nafl Salaat after the Fardh of Asr. Qadha Salaat, however, may be performed after the Fardh of Asr. However, one should perform Qadha Salaah in this time in privacy.
