The Prophet (may Allah's peace and blessings be upon him) used to say between the two prostrations: "Rabbi ighfir li, rabbi ighfir li" (My Lord, forgive me; my Lord, forgive me)
Authenticعن حُذَيْفَةَ رضي الله عنه: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ بَيْنَ السَّجْدَتَيْنِ: «رَبِّ اغْفِرْ لِي، رَبِّ اغْفِرْ لِي».
Hudhayfah (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) used to say between the two prostrations: "Rabbi ighfir li, rabbi ighfir li" (My Lord, forgive me; my Lord, forgive me).
Explanation
When the Prophet (may Allah's peace and blessings be upon him) sat between the two prostrations, he would say: My Lord, forgive me; my Lord, forgive me, repeatedly. "My Lord, forgive me" means: The servant asks his Lord to eliminate his sins and conceal his faults.
Benefits
- It is prescribed to say this supplication between the two prostrations in obligatory and supererogatory prayers.
- It is recommended to repeat the phrase: "My Lord, forgive me." The obligation is one time.
