Ibn ‘Abbas reported God’s messenger as saying, “The devil is couching at the heart of the son of Adam. When he mentions God he withdraws, but when he is neglectful he makes evil suggestions.”
Abu Sa'id said God’s messenger was asked who would be most excellent and most exalted in degree in God’s estimation on the day of resurrection, and replied, “The men and women who make frequent mention of God.” He was asked if they would be superior even to the man who had fought in God’s path, and replied, “Even though he plied his sword among infidels and polytheists till it was broken and smeared with blood, the one who made mention of God would have a more excellent degree than he.”
Ahmad and Tirmidhi transmitted it, the latter saying this is a gharib tradition.
Malik said he heard God’s messenger used to say, “The one who makes mention of God among those who are negligent is like one who goes on fighting after others have fled; the one who makes mention of God among those who are negligent is like a green branch upon a withered tree; (A version has, “Like a green tree amidst the trees”); the one who makes mention of God among those who are negligent is like a lamp in a dark house; the one who makes mention of God among those who are negligent will be shown by God during his lifetime his resting-place in paradise; and the one who makes mention of God among those who are negligent will be forgiven as many sins as the number of those who have the faculty of speech (fasih) and those who are destitute of it (a'jam)” Fasih refers to human beings and a'jam to animals.
وَعَن عبد الله بن يسر: أَنَّ رَجُلًا قَالَ: يَا رَسُولَ اللَّهِ إِنَّ شَرَائِعَ الْإِسْلَامِ قَدْ كَثُرَتْ عَلَيَّ فَأَخْبِرْنِي بِشَيْءٍ أَتَشَبَّثُ بِهِ قَالَ: " لَا يَزَالُ لِسَانُكَ رَطْبًا بِذكر اللَّهِ)
رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيث حسن غَرِيب
‘Abdallah b. Busr told of a man saying, “Messenger of God, the ordinances of Islam are too many for me, so tell me something to which I may cling.” He replied, “Your tongue will continue to be supple by making mention of God.”
Tirmidhi and Ibn Majah transmitted it. Tirmidhi saying this is a hasan gharib tradition.
