Chapter 147 | The Case of One Who Forgets Taqsir until Talbiyah (Here I Am, O Lord, to obey Your command) for al-Hajj or Shaves His Head or Has Carnal Relations with His Wife
2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنْ رَجُلٍ أَهَلَّ بِالْعُمْرَةِ وَنَسِيَ أَنْ يُقَصِّرَ حَتَّى دَخَلَ فِي الْحَجِّ قَالَ يَسْتَغْفِرُ الله وَلا شَيْءَ عَلَيْهِ وَتَمَّتْ عُمْرَتُهُ.
2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah , about a man who commences al-‘Umrah but then forgets Taqsir (cutting some hair or finger nails and so on) until he enters al-Hajj. He (the Imam) said, ‘He must ask forgiveness from Allah. He is not obligated for anything in this matter. His al-‘Umrah is complete.’”
