(14) To love the Messenger (Muhammad) is a part of faith
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ: أَخْبَرَنَا شُعَيْبٌ، قَالَ: حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الْأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، أَن رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: "فَوَالَّذِي نَفْسِي بِيَدِهِ، لَا يُؤْمِنُ أَحَدُكُمْ حَتَّى أَكُونَ أَحَبَّ إِلَيْهِ مِنْ وَالِدِهِ وَوَلَدِهِ".
Sahih hadith: Narrated Abu Huraira: Allah's Apostle said, By Him in Whose Hands my life is, none of you will have faith till he loves me more than his father and his children.

(9) (What is said) regarding the deeds of faith
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، قَالَ: حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ، قَالَ: حَدَّثَنَا سُلَيْمَانُ بْنُ بِلَالٍ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْه، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: "الْإِيمَانُ بِضْعٌ وَسِتُّونَ شُعْبَةً، وَالْحَيَاءُ شُعْبَةٌ مِنَ الْإِيمَانِ".
Sahih hadith: Narrated Abu Huraira: The Prophet said, Faith (Belief) consists of more than sixty branches (i.e. parts). And Haya (This term Haya covers a large number of concepts which are to be taken together; amongst them are self respect, modesty, bashfulness, and scruple, etc.) is a part of faith.
