They were commanded to pray inside Their Homes

Allah tells us why He saved the Children of Israel from Fir`awn and his people. He tells us how he saved them. Allah commanded Musa and his brother Harun to take houses for their people in Egypt,

وَاجْعَلُواْ بُيُوتَكُمْ قِبْلَةً

Commentary

Mentioned in the verses appearing immediately above, there are some circumstantial details along with their corresponding injunctions as they relate to Sayyidna Musa and Sayyidna Harun (علیہما السلام) and the children of Isra'il and the people of the Pharaoh. The first verse (87) carries an injunction pertaining to a particular event. Banu Isra'il (the children of Isra'il) who observed the religious law of Sayyidna Musa (علیہ السلام) used to perform their prayers only in their synagogues as customary. Then, the past communities were also bound by this injunction. Their prayers were not valid if performed in their homes. The Muslim Ummah was the special recipient of the convenience that they could, if needed, perform their prayers everywhere as they wished. In a Hadith of Sahih Muslim, the Holy Prophet ﷺ has, out of his six singularities, given one as, ` the whole earth has been made a masjid for me.' It means that Salah performed anywhere remains valid. However, it is something else that the performing of obligatory prayers in congregation only in masjids has been declared as an emphasized Sunnah. Then, saying nafl prayers inside homes is better. This was the usual practice of the Holy Prophet i He would say only the Fard Salah in the Masjid then go home and say his sunnahs and nafls there. As for the Banu Isra'il, they were bound to offer their prayers only in their synagogues in obedience to their religious laws. Realizing this, the Pharaoh who used to oppress them in all sorts of ways had all synagogues demolished so that they could be deprived of offering their prayers in accordance with their religious laws. Thereupon, Allah Ta` ala sent to the two prophets of Banu Isra'il, Sayyidna Musa and Harun, may peace be on them both, the injunction mentioned in verse 87. It was said there that new houses should be built in Egypt for Bani Isra'il and that their orientation should be towards the Qiblah so that prayers could be offered in those very residential houses.
