Surah Yunus, ayah 87

10:87

وَأَوۡحَيۡنَآ إِلَىٰ مُوسَىٰ وَأَخِيهِ أَن تَبَوَّءَا لِقَوۡمِكُمَا بِمِصۡرَ بُيُوتٗا وَٱجۡعَلُواْ بُيُوتَكُمۡ قِبۡلَةٗ وَأَقِيمُواْ ٱلصَّلَوٰةَۗ وَبَشِّرِ ٱلۡمُؤۡمِنِينَ ٨٧

Wa awhaynā ilā mūsā wa akhīhi an tabawwa'ā liqawmikumā bimisra buyūtan waj'alū buyūtakum qiblatan wa aqīmus-salawāta wabasshiril-mu'minīn

And We inspired to Moses and his brother, "Settle your people in Egypt in houses and make your houses [facing the] qiblah537 and establish prayer and give good tidings to the believers."
