The habit of doing istighfār is a way out from all grief and is a means for increase in one's rizq (provisions)
The Messenger of Allah ﷺ said, "If anyone makes it a habit to seek forgiveness, Allah will make a way out for him from every constraint, and give him relief from every distress, and will provide rizq for him from where he does not expect."
قَالَ رَسُولُ اللَّهِ ﷺ: «مَنْ لَزِمَ الاِسْتِغْفَارَ، جَعَلَ اللَّهُ لَهُ مِنْ كُلِّ ضِيقٍ مَخْرَجًا، وَمِنْ كُلِّ هَمٍّ فَرَجًا، وَرَزَقَهُ مِنْ حَيْثُ لاَ يَحْتَسِبُ۔»
