سَعْدُ بْنُ عَبْدِ اَللَّهِ عَنْ مُحَمَّدِ بْنِ اَلْحُسَيْنِ عَنْ مُوسَى بْنِ عُمَرَ عَنْ عَبْدِ اَللَّهِ بْنِ اَلْمُغِيرَةِ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ نَجْمَعُ بَيْنَ اَلْمَغْرِبِ وَ اَلْعِشَاءِ فِي اَلْحَضَرِ قَبْلَ أَنْ تَغِيبَ اَلشَّمْسُ مِنْ غَيْرِ عِلَّةٍ قَالَ «لاَ بَأْسَ»
Sa'd ibn Abdullah narrated from Muhammad ibn Al-Husayn from Musa ibn Umar from Abdullah ibn Al-Mughira from Ishaq ibn Ammar who said:
I asked Abu Abdillah عليه السلام, peace be upon him: “May we combine between Maghrib and Isha while residing, before the twilight disappears, without any excuse?” Imam عليه السلام said: "There is no harm."
