Your article regarding Ifṭār duʿās does not mention the common duʿāʾ:
اللهم لك صمت وبك آمنت وعليك توكلت وعلى رزقك أفطرت
Is there any narration to substantiate this duʿāʾ at the time of Ifṭār?
بسم الله الرحمن الرحیم
Answer:
This duʿāʾ or similar duʿās with variation in the words have been mentioned by several Ḥanafī jurists[1] and the Ḥanbalī scholar ʿAllāmah Ibn al-Jawzī (d. 597/1201)[2]. However, Mullā ʿAlī al-Qārī (d. 1014/1605) suggests that there is no basis for the addition of وبك آمنت and وعليك توكلت وبصوم غد نویت although their meaning is sound.[3] It is therefore more virtuous to read the supplications narrated in the Aḥādīth, as outlined in my article. It is worth noting that in addition to the duʿās listed therein, there is a narration outlined in the Arabic references therein that mentions the following duʿāʾ which can also be read:
اللهم لك صمت وعليك توكلت وعلى رزقك أفطرت
Ḥāfiẓ Ibn Ḥajar al-ʿAsqalānī (d. 852/1449) explains that it is necessary to protect the words of the duʿās that have been transmitted in Aḥādīth because they possess unique characteristics and benefits.[4] The famous muḥaddith Shaykh Rashīd Aḥmad Gangohī (d. 1323/1905) further suggests that a person’s duʿāʾ is more likely to be accepted if he supplicates with the words used by the Prophet ﷺ.[5]
