Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 83
فِي كِتَابِ مُحَمَّدِ بْنِ أَحْمَدَ بْنِ يَحْيَى بْنِ عِمْرَانَ اَلْأَشْعَرِيِّ عَنْ إِبْرَاهِيمَ بْنِ هَاشِمٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ يَرْفَعُهُ إِلَى أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلرَّجُلِ يَحْزُنُهُ اَلْأَمْرُ وَ يُرِيدُ اَلْحَاجَةَ قَالَ «يُصَلِّي رَكْعَتَيْنِ وَ يَقْرَأُ فِي إِحْدَاهُمَا، «قُلْ هُوَ اَللّٰهُ أَحَدٌ» أَلْفَ مَرَّةٍ وَ فِي اَلْأُخْرَى مَرَّةً ثُمَّ يَسْأَلُ حَاجَتَهُ.
In the book of Muhammad ibn Ahmad ibn Yahya ibn Imran al-Ash'ari, narrated by Ibrahim ibn Hashim, from Muhammad ibn Sinan, raised to Imam Jafar ibn Muhammad Al-Sadiq عليه السلام regarding a man troubled by a matter and in need of something, Imam عليه السلام said: "He should pray two rak'ahs and recite in one of them 'Qul Huwa Allahu Ahad' (Surah Al-Ikhlas) a thousand times, and in the other rak'ah he should recite it once, then ask for his need."
