Bilal b. Harith al-Muzani reported God’s messenger as saying, “Whoever revives a sunna of mine which has been neglected after my time will have a reward equal to the rewards of those who act upon it, without their rewards being diminished in any way. But whoever invents a misleading innovation with which God and His messenger are not pleased will be charged with a sin equal to the sins of those who act upon it without that diminishing their loads in any way.”
Tirmidhi transmitted it, and Ibn Majah transmitted it from Kathir b. ‘Abdallah b. ‘Amr from his father from his grandfather.
‘Abdallah b. ‘Amr reported God’s messenger as saying, “None of you is a believer till his desire follows what I have brought.”
He transmitted it in Sharh al-sunna ; and an-Nawawi said in his Arba’in, “This is a sound tradition which we have transmitted in Kitab al-hujja with a sound isnad.”
‘Amr b. ‘Auf reported God’s messenger as saying, “The religion will shrink back to the Hijaz as a snake shrinks back to its hole, and the religion will seek refuge in the Hijaz as the mountain goat seeks refuge in the mountain top. The religion began few in number and will return to the state in which it began. Blessed are the few, for they will set right the corruptions caused in my sunna by people after my death.”
‘Abdallah b. Mas'ud told how God’s messenger drew a line for them and then said, “This is God’s path.” Thereafter he drew several lines on his right and left and said, “These are paths on each of which there is a devil who invites people to follow it.” And he recited, “And that this is my path, straight; follow it...” 1
