Hadith 22149

حَدَّثَنَا عَبْدُ الصَّمَدِ , حَدَّثَنَا شُعْبَةُ , حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي يَعْقُوبَ الضَّبِّيُّ , قَالَ : سَمِعْتُ أَبَا نَصْرٍ يُحَدِّثُ , عَنْ رَجَاءِ بْنِ حَيْوَةَ , عَنْ أَبِي أُمَامَةَ , قَالَ : أَتَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ , فَقُلْتُ : مُرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ , قَالَ : " عَلَيْكَ بِالصَّوْمِ , فَإِنَّهُ لَا عِدْلَ لَهُ " , ثُمَّ أَتَيْتُهُ الثَّانِيَةَ , فَقَالَ : " عَلَيْكَ بِالصِّيَامِ " .
It is narrated from Hazrat Abu Umamah (may Allah be pleased with him) that once I presented myself before the Noble Prophet (peace and blessings be upon him) and requested, "Command me to do an action that will admit me into Paradise." The Noble Prophet (peace and blessings be upon him) said, "Make fasting obligatory upon yourself, for there is no deed like fasting." Then I again presented myself in the court of the Messenger (peace and blessings be upon him), and the Noble Prophet (peace and blessings be upon him) said, "Continue to make fasting obligatory upon yourself."
