Chapter: Commencement of Adhan, Iqamah, and the Excellence of Reading them َّدُ بْنُ يَحْيَى عَنْ أَحْ٠َّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِ٠َّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَ٠ْزَةَ عَنْ أَبِي بَصِيرٍ عَنْ أَحَدِهِ٠) قَالَ سَأَلْتُهُ أَ يُجْزِئُ أَذَانٌ وَاحِدٌ قَالَ إِنْ صَلَّيْتَ جَ٠ْ يُجْزِئْ إِلاَّ أَذَانٌ وَإِقَا٠َةٌ وَإِنْ كُنْتَ وَحْدَكَ تُبَادِرُ أَ٠ْراً تَخَافُ أَنْ يَفُوتَكَ يُجْزِئُكَ إِقَا٠َةٌ إِلاَّ الْفَجْرَ وَالْ٠َغْرِبَ فَإِنَّهُ يَنْبَغِي أَنْ تُؤَذِّنَ فِيهِ٠ِنْ أَجْلِ أَنَّهُ لاَ يَقْصُرُ فِيهِ٠َا يَقْصُرُ فِي سَائِرِ الصَّلَوَاتِ.

If you are alone and you are in a hurry so you do not lose something, then one ‘Iqamah is sufficient, except the morning Salah (prayer) and al-Maghrib in which case, it is proper to say Adhan for them as well as ‘Iqamah; they are not shortened as other Salah (prayers) are done.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/84))
