As part of the daily after Fajr program regarding the life of a Muslim, the following is the explanation of Istigfaar – seeking the forgiveness of Allah Ta’ala
Rasulullah Sallalahu alayhi wa Sallam used to recite :
أستغفرالله ~ Astagfirullah (I seek forgiveness of Allah)
at least 100 times a day.
Ponder on what type of life do we want to enjoy? A heedless life of committing sinful haraam acts or a life of taqwa and piety? When we are weak and feeble in our obedience to Allah Subhanahu Wa Ta’ala, the word Taqwa (piety) that we so often hear, seems so difficult to attain. However, when we decide to take that baby step towards Allah Subhanahu Wa Ta’ala, He will most definitely come running towards us! Through regular Taubah (repentance) and Istighfaar (seeking forgiveness), one can gain the enjoyment of Taqwa… [Moulana Naeem Motala – Daamat Barakaatuhum]
A person who says :
أَسْتَغْفِرُ اللَّهَ الْعَظِيمَ الَّذِي لاَ إِلَهَ إِلاَّ هُوَ الْحَيُّ الْْقَيُّومُ وَ أَتُوبُ إِلَيْهِ
Transliteration: “Astaghfirullah al-’Azeem al-lazi la ilaha illa Huwal-Hayyul-Qayyum wa atubu ilaih ”
Translation: I seek the forgiveness of Allah the Mighty, Whom there is none worthy of worship except Him, The Living, The Eternal, and I repent unto Him
even if he has committed sins as much as the the foam of an ocean, still he will be forgiven.
[Abu Dawud- 2:85/ Tirmidhi 5:569]
عَنْ أَبِي سَعِيدٍ، رضى الله عنه عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ : مَنْ قَالَ حِينَ يَأْوِي إِلَى فِرَاشِهِ أَسْتَغْفِرُ اللَّهَ الْعَظِيمَ الَّذِي لاَ إِلَهَ إِلاَّ هُوَ الْحَىَّ الْقَيُّومَ وَأَتُوبُ إِلَيْهِ. ثَلاَثَ مَرَّاتٍ غَفَرَ اللَّهُ ذُنُوبَهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ
Hazrat Abdullah bin Abbas Radiyallahu Anhu narrates that Rasulullah Sallallahu Alayhi Wasallam said: “The one who [regularly] says Istighfaar, Allah Azza Wa-Jal will open a path for him from all difficulties, remove him from all sorrow, and grant him sustenance from unimagined and unexpected sources.” ~ [Abu Dawud]
