My father رحمه الله said, it was narrated to me by Saʿd bin ʿAbd Allāh, from Salamah bin al-Khaṭṭāb, from Moḥammed ibn ʿĪsa al-Armani, from Abī ʿImrān, al-Kharrāṭ, from Bishr al-‘Awzāʿi:

From Jaʿfar bin Moḥammed, from his father, from his forefathers عليهم السلام who said: Whoever says ‘There is no god but Allāh, truly and in all truth; there is no god but Allāh, in belief and affirmation; there is no god but Allāh, servitude and serfdom is for Him’ (Lā Ilāha Ila Allāh, Ḥaqqan, Ḥaqqā; Lā Ilāha Ila Allāh, ‘Imānan wa-Tasdīqā; Lā Ilāha Ila Allāh, ʿUbūdīyatan wa-Riqqā) fifteen times, everyday – Allāh will turn to him with His face and will not turn away from him until he will enter the Paradise.

أبي (ره) قال حدثني سعد بن عبد الله عن سلمة بن الخطاب عن محمد ابن عيسى الأرمني عن أبي عمران الخراط عن بشر الأوزاعي عن جعفر ابن محمد عن أبيه عن آبائه عليهم السلام قال من قال في كل يوم خمس عشرة مرة لا إله إلا الله حقا حقا لا إله إلا الله ايمانا وتصديقا لا إله إلا الله عبودية ورقا أقبل الله عليه بوجهه فلم يصرف عنه وجهه حتى يدخل الجنة
