Hadith 12414ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ قُلْتُ لَهُ أَدْنَى مَا يُجْزِئُ الْمَرِيضَ مِنَ التَّسْبِيحِ فِي الرُّكُوعِ وَالسُّجُودِ قَالَ تَسْبِيحَةٌ وَاحِدَةٌ.
4. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus ibn ‘Abd al-Rahman from Mu‘awiyah ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah (a.s.), ’How many Tasbih is sufficient in Ruku’ (bowing down on one’s knees) and in Sujud (prostration) in the case of one suffering from illness?’ He (the Imam) said, ‘One Tasbih is sufficient.’”
