This fartwa also includes the hadith that inadvertently admits that Muhammad was an arsonist:
Praying salah with congregation has been greatly emphasized in Shariah. Consider the following hadith:
عن أبى هريرة قال قال رسول الله صلى الله عليه وسلم لقد هممت أن آمر فتيتى فيجمعوا حزما من حطب ثم آتى قوما يصلون فى بيوتهم ليست بهم علة فأحرقها عليهم (ابو داود)
Abu Hurairah (Radhiyallahu Anhu) narrates that the Prophet (Sallalahu Alaihi Wasallam) said, “I instruct some youngsters to collect firewood then I go to those who perform prayer at their homes without a valid reason and set their houses on fire” (Abdu Dawood)
If one prays his salah at home without a sound excuse, his salah will be valid, but it is very much disliked. The place for fardsalah is the masjid. In the time of Rasulullah (Sallalahu Alaihi Wasallam) and in the time Sahaba, only an open hypocrite would miss the congregational prayer without a valid excuse.
