عَنْهُ عَنْ مُحَمَّدِ بْنِ زِيَادٍ عَنْ عَبْدِ اَللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« وَقْتُ اَلْمَغْرِبِ مِنْ حِينِ تَغِيبُ اَلشَّمْسُ إِلَى أَنْ تَشْتَبِكَ اَلنُّجُومُ»
From him, from Muhammad ibn Ziyad, from Abdullah ibn Sinan:
Abu Abdillah عليه السلام, peace be upon him, said: "The time for Maghrib is from when the sun sets until the stars become intertwined."
