Chapter 2 | Those Who Preserve Salah (prayer) and Those Who Lose
3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ يُونُسَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ قِيلَ لَهُ وَأَنَا حَاضِرٌ الرَّجُلُ يَكُونُ فِي صَلاَتِهِ خَالِياً فَيَدْخُلُهُ الْعُجْبُ فَقَالَ إِذَا كَانَ أَوَّلَ صَلاَتِهِ بِنِيَّةٍ يُرِيدُ بِهَا رَبَّهُ فَلاَ يَضُرُّهُ مَا دَخَلَهُ بَعْدَ ذَلِكَ فَلْيَمْضِ فِي صَلاَتِهِ وَلْيَخْسَأِ الشَّيْطَانَ.
3. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus ibn ‘Abd al-Rahman from Yunus ibn ‘Ammar who has said the following: “Someone asked abu ‘Abd Allah , while I was present, ‘What is the rule about a man who is in Salah (prayer) free of negative feelings but then he feels self-importance?’ Imam replied, ‘If in the beginning his intention was only for his Lord, then such feeling does not affect his prayer negatively, he should continue his Salah (prayer) and Satan is humiliated.’”
