Seek forgiveness for freedom from grief

The following hadith is weak. Shiekh Ibn Uthaymiin says it is authentic in meaning.

من لزم الاستغفار جعل الله له من كل هم فرجا ومن كل ضيق مخرجا ورزقه من حيث لا يحتسب

He who makes istighfaar necessary [upon himself], Allaah will make for him freedom from grief and an exit from every constraining [circumstances]. And He will provide him rizQ from where he does not expect.

هذا الحديث ضعيف ، ولكن معناه صحيح ؛ لأن الله تعالى قال : ( وَأَنْ اسْتَغْفِرُوا رَبَّكُمْ ثُمَّ تُوبُوا إِلَيْهِ يُمَتِّعْكُمْ مَتَاعاً حَسَناً إِلَى أَجَلٍ مُسَمًّى وَيُؤْتِ كُلَّ ذِي فَضْلٍ فَضْلَهُ ) ، وقال تعالى عن هود : ( وَيَا قَوْمِ اسْتَغْفِرُوا رَبَّكُمْ ثُمَّ تُوبُوا إِلَيْهِ يُرْسِلْ السَّمَاءَ عَلَيْكُمْ مِدْرَاراً وَيَزِدْكُمْ قُوَّةً إِلَى قُوَّتِكُمْ وَلا تَتَوَلَّوْا مُجْرِمِينَ ) ، ولا شك أن الاستغفار سبب لمحو الذنوب ، وإذا محيت الذنوب تخلفت آثارها المرتبة عليها ، وحينئذٍ يحصل للإنسان الرزق والفرج من كل كرب ، ومن كل هم ، فالحديث ضعيف السند ، لكنه صحيح المعنى " انتهى .

This hadith is weak but its meaning is Sahiih because Allaah has said:

And [saying], "Seek forgiveness of your Lord and repent to Him, [and] He will let you enjoy a good provision for a specified term and give every doer of favor his favor. But if you turn away, then indeed, I fear for you the punishment of a great Day.

[Qur'aan 11:3]

And O my people, ask forgiveness of your Lord and then repent to Him. He will send [rain from] the sky upon you in showers and increase you in strength [added] to your strength. And do not turn away, [being] criminals."

[Qur'aan 11:52]

There is no doubt that istighfaar is a means to wiping out sins. When sins are wiped out, their effects, which were to be, are deterred. Then a person attains rizQ and freedom from every difficulty and sadness. The hadiith is weak in chain but authentic in meaning.
