Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
muslim:251b – [Chain 1] Isḥāq b. Mūsá al-Anṣārī > Maʿn > Mālik [Chain 2] Muḥammad b. al-Muthanná > Muḥammad b. Jaʿfar > Shuʿbah Jamīʿ

This hadith has been narrated on the authority of ʿAli b. ʿAbd al-Rahman with the same chain of transmitters and there is no mention of the word of al-Ribat in the hadith transmitted by Shuʿba and in the hadith narrated by Malik "Ribat" has been mentioned twice. This is the "Ribat" for you, this is the "Ribat" for you.  

مسلم:٢٥١b – حَدَّثَنِي إِسْحَاقُ بْنُ مُوسَى الأَنْصَارِيُّ حَدَّثَنَا مَعْنٌ حَدَّثَنَا مَالِكٌ ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ جَمِيعًا

عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ بِهَذَا الإِسْنَادِ  

وَلَيْسَ فِي حَدِيثِ شُعْبَةَ ذِكْرُ الرِّبَاطِ وَفِي حَدِيثِ مَالِكٍ ثِنْتَيْنِ فَذَلِكُمُ الرِّبَاطُ فَذَلِكُمُ الرِّبَاطُ
