Hadith 114121ـ وَبِهَذَا الإِسْنَادِ عَنْ صَالِحِ بْنِ عُقْبَةَ عَنْ سُلَيْمَانَ بْنِ صَالِحٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ لاَ يُقِمْ أَحَدُكُمُ الصَّلاَةَ وَهُوَ مَاشٍ وَلاَ رَاكِبٌ وَلاَ مُضْطَجِعٌ إِلاَّ أَنْ يَكُونَ مَرِيضاً وَلْيَتَمَكَّنْ فِي الإِقَامَةِ كَمَا يَتَمَكَّنُ فِي الصَّلاَةِ فَإِنَّهُ إِذَا أَخَذَ فِي الإِقَامَةِ فَهُوَ فِي الصَّلاَةِ.
21. Through the same chain of narrators as that of the previous Hadith the following is narrated from Salih ibn ‘Uqbah from Sulayman ibn Salih who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘No one among you says ‘Iqamah for Salah (prayer) when walking, riding or resting unless one is ill. One remains well placed during ‘Iqamah like in Salah (prayer). In ‘Iqamah one is in Salah (prayer).’”
