When is the “hour of response” on Friday?
Shaykh Ibn Baaz, Majallat al-Buhooth, issue no. 34, p. 14
It lasts from after ‘Asr until the sun sets, for those who sit and wait for Maghrib, whether that is in the mosque or at home, making du’aa’ to their Lord, whether they are men or women; whoever does that is more deserving of seeing a response to his or her du’aa’. But men should not pray Maghrib or any other prayer at home unless they have a legitimate shar’i excuse, as is well known from the evidence of sharee’ah.
