Islamic Ruling on Thankfulness Prayer Salat al Shukr
According to Islamic scholars, praying two rakah and performing a prostration of thanks at times of happiness is supported by hadith and is considered recommended.
The Islamic ruling on the thankfulness prayer is based on authentic narrations. Abu Bakrah reported that whenever the Prophet Muhammad peace be upon him received good news or felt happiness, he would fall into prostration to thank Allah. This is recorded in Sunan Abi Dawood 2774.
Another narration from Abdullah ibn Abi Awfa states that when the Prophet peace be upon him received the good news of Abu Jahl being killed, he prayed two rakah. This is recorded in Sunan Ibn Majah 1391.
From these narrations, Islamic scholars explain in their fatwa that the Prophet peace be upon him performed two rakah prayer at times of happiness and also performed prostration of thanks. Because of these hadiths, jurists have written that when a person receives a blessing or a hardship is removed, it is recommended to pray two rakah as a thankfulness prayer and also to perform Sajdah al Shukr.
Classical scholars mention that giving charity or praying a thankfulness prayer along with Sajdah al Shukr is a good and recommended act. These references are mentioned in Al Majmu and Nihayat al Muhtaj. Therefore, it is better to perform Sajdah al Shukr and also pray two rakah with the intention of a Sunnah prayer. This is the Islamic ruling as explained by Islamic scholars.
