Sahih Muslim Book - 13, Hadith - 2652

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى أَخْبَرَنَا شَيْبَانُ عَنْ أَشْعَثَ بْنِ أَبِى الشَّعْثَاءِ عَنْ جَعْفَرِ بْنِ أَبِى ثَوْرٍ عَنْ جَابِرِ بْنِ سَمُرَةَ - رضى الله عنه - قَالَ كَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- يَأْمُرُنَا بِصِيَامِ يَوْمِ عَاشُورَاءَ وَيَحُثُّنَا عَلَيْهِ وَيَتَعَاهَدُنَا عِنْدَهُ فَلَمَّا فُرِضَ رَمَضَانُ لَمْ يَأْمُرْنَا وَلَمْ يَنْهَنَا وَلَمْ يَتَعَاهَدْنَا عِنْدَهُ.

It was narrated that Jabir bin Samurah [may Allah be pleased with them] said: “The Messenger of Allah used to enjoin us, and encourage us, to fast on the day of Ashura, and he used to check on us when that day came, When (fasting during) Ramadan was enjoined, he neither commanded us nor forbade us, and he did not check on us.”
