[Machine] My father used to sit facing the qibla and wouldn't speak until the sun rose after he prayed Fajr. Sometimes I would speak to him about a need, but he wouldn't respond. So, I asked him, "What is this?" He said, "I heard the Messenger of Allah ﷺ say, 'Whoever prays Fajr and then recites 'Say: He is Allah, the One' one hundred times before speaking, every time he recites it, one year's worth of sins will be forgiven for him.'"
كَانَ أَبِي إِذَا صَلَّى الصُّبْحَ جَلَسَ مُسْتَقْبِلَ الْقِبْلَةِ لَا يَتَكَلَّمُ حَتَّى تَطْلُعَ الشَّمْسُ فَرُبَّمَا كَلَّمْتُهُ فِي الْحَاجَةِ فَلَا يُكَلِّمُنِي فَقُلْتُ مَا هَذَا؟ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ صَلَّى الصُّبْحَ ثُمَّ قَرَأَ قُلْ هُوَ اللهُ أَحَدٌ مِائَةَ مَرَّةً قَبْلَ أَنْ يَتَكَلَّمَ فَكُلَّمَا قَرَأَ قُلْ هُوَ اللهُ أَحَدٌ غُفِرَ لَهُ ذَنْبُ سَنَةٍ»
