3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيهِ السَّلام) اغْتَنِمُوا الدُّعَاءَ عِنْدَ أَرْبَعٍ عِنْدَ قِرَاءَةِ الْقُرْآنِ وَعِنْدَ الأذَانِ وَعِنْدَ نُزُولِ الْغَيْثِ وَعِنْدَ الْتِقَاءِ الصَّفَّيْنِ لِلشَّهَادَةِ.
3. Ali Ibn Ibrahim has narrated from his father from al-Nawfali from al-Sakuni from Abu ‘Abdillah (al-Sadiq) عليه السلام that Amir al-Mu'minin عليه السلام said: "Take advantage of supplication at four times: during the recitation of the Quran, at the call to prayer (Adhan), when rain falls, and at the meeting of the two armies for battle."
