Hadith 1190
عَنْ سَهْلِ بْنِ مُعَاذٍ عَنْ أَبِيهِ (رَضِيَ اللَّهُ عَنْهُ) عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ: ((مَنْ قَعَدَ فِي مُصَلَّاهُ حِينَ يُصَلِّي الصُّبْحَ حَتَّى يُسَبِّحَ الضُّحَى لَا يَقُولُ إِلَّا خَيْرًا غُفِرَتْ لَهُ خَطَايَاهُ وَإِنْ كَانَتْ أَكْثَرَ مِنْ زَبَدِ الْبَحْرِ))
Sayyiduna Mu'adh (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever, after performing the Fajr prayer, sits at his prayer place until he performs the Duha prayer, and during this period speaks only good words, his sins will be forgiven, even if they are more than the foam of the sea.
Hadith 1191
عَنْ جَابِرِ بْنِ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا صَلَّى الْغَدَاةَ جَلَسَ فِي مُصَلَّاهُ حَتَّى تَطْلُعَ الشَّمْسُ حَسَنَاءَ أَوْ تَرْتَفِعَ الشَّمْسُ حَسَنَاءَ
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) performed the Fajr prayer, he would remain seated on his prayer mat until the sun had risen well or had become high.
