It was narrated to us by my father رحمه الله, who said – it was narrated to us by ʿAlī bin Mūsa al-Kamandāni, who said – it was narrated to us by Aḥmed bin Moḥammed binʿĪsa, from ʿAlī bin al-Ḥussain, from Moḥammed bin ʿUbayd, from ʿUbayd bin Hārūn, who said – it was narrated to us by Abū Yazīd, from Ḥuṣṣain, from al-Ṣādiq Jaʿfar bin Moḥammed, from his father, from his forefathers عليهم السلام, who said:

‘Amīr al-Mu’minīn عليه السلام said: Upon you [is the responsibility] of seeking forgiveness and supplication in abundance during the Month of Ramadhān. As for supplication, it prevents calamities falling upon you. As for seeking forgiveness, it wipes away your sins.

حدثنا أبي ( رحمه الله ) ، قال : حدثنا علي بن موسى الكمنداني ، قال : حدثنا أحمد بن محمد بن عيسى ، عن علي بن الحسين ، عن محمد بن عبيد ، عن عبيد بن هارون ، قال : حدثنا أبو يزيد ، عن حصين ، عن الصادق جعفر بن محمد ، عن أبيه ، عن آبائه ( عليهم السلام ) ، قال : قال أمير المؤمنين ( عليه السلام ) : عليكم في شهر رمضان بكثرة الاستغفار والدعاء ، فأما الدعاء فيدفع عنكم به البلاء ، وأما الاستغفار فتمحى به ذنوبكم .
