Reward of reciting Surah Tauheed
Thawāb al-Aʿmāl wa ʿiqāb al-Aʿmāl|Volume 1|Book 2|Chapter 263
وَ بِهَذَا الْإِسْنَادِ عَنِ الْحَسَنِ عَنْ سَیْفِ بْنِ عَمِیرَهَ عَنْ ابن [أَبِی] بَکْرٍ الْحَضْرَمِیِّ عَنْ أَبِی عَبْدِ اللَّهِ ع قَالَ: مَنْ کانَ یُؤْمِنُ بِاللَّهِ وَ الْیَوْمِ الْآخِرِ فَلَا یَدَعْ أَنْ یَقْرَأَ فِی دُبُرِ الْفَرِیضَهِ بِ قُلْ هُوَ اللَّهُ أَحَدٌ فَإِنَّهُ مَنْ قَرَأَهَا جَمَعَ اللَّهُ لَهُ خَیْرَ الدُّنْیَا وَ الْآخِرَهِ وَ غَفَرَ اللَّهُ لَهُ وَ لِوَالِدَیْهِ وَ مَا وَلَدَ.
4. And from the previous chain from al-Hassan from Sayf b. ’Umayra from Ibn [Abi] Bakr al-Hadhrami from Abi Abdillah عليه السلام who said: “One who has faith on Allah and the Day of Judgment it is necessary for him to recite Surah Tauheed in his obligatory prayers. If a person does so Allah will grant him goodness in this world and the hereafter and will forgive him, his parents and his children.”
