[Machine] The Messenger of Allah ﷺ said, "Whoever prays a prescribed prayer with the imam, let him recite the opening chapter of the book (i.e., Al-Fatiha) silently. And whoever reaches the mother of the book (i.e., Surah Al-Fatiha), then he has completed his prayer."
قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ صَلَّى صَلَاةً مَكْتُوبَةً مَعَ الْإِمَامِ فَلْيَقْرَأْ فَاتِحَةَ الْكِتَابِ فِي سَكَتَاتِهِ وَمَنِ انْتَهَى إِلَى أُمِّ الْكِتَابِ فَقَدْ أَجْزَأَهُ» وَمِنْهَا
