عَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يُعْجِبُهُ أَنْ يَدْعُوَ ثَلَاثًا وَيَسْتَغْفِرَ ثَلَاثًا
It is narrated from Sayyiduna Abdullah bin Masood (may Allah be pleased with him) that it was beloved to the Noble Prophet (peace and blessings be upon him) to supplicate three times and to seek forgiveness three times.
