وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ لَزِمَ الِاسْتِغْفَارَ جَعَلَ اللَّهُ لَهُ مِنْ كُلِّ ضِيقٍ مَخْرَجًا وَمِنْ كُلِّ هَمٍّ فَرَجًا وَرَزَقَهُ مِنْ حَيْثُ لَا يَحْتَسِبُ» . رَوَاهُ أحمدُ وَأَبُو دَاوُد وَابْن مَاجَه

He reported God’s messenger as saying, “If anyone continually asks pardon, God will appoint for him a way out of every distress and a relief from every anxiety, and will provide for him from where he did not reckon.” Ahmad, Abu Dawud and Ibn Majah transmitted it.
