An-Nawawi Hadith - 31

عَنْ أَبِي الْعَبَّاسِ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ رَضِيَ اللهُ عَنْهُ قَالَ جَاءَ رَجُلٌ الَى النَّبِيِّ صَلَي اللهُ عَلَيْهِ وَ سَلَمَ فَقَالَ: يَا رَسولَ الله دُلَّنِي عَلَى عَمَلٍ إِذَا عَمِلْتُهُ اَحَبَنِيَ اللهُ وَ اَحَبَنِيَ النَّاسُ فَقَالَ: ازْهَدْ فِي الدُّنْيَا يُحِبَّكَ اللهُ وَ ازْهَدْ فِي مَا عِنْدَ النَّاسِ يُحِبَّكَ النَّاسُ حَدِيثٌ حَسَنٌ رَوَاهُ ابْنُ مَاجَه وَ غَيْرُهُ بِأَسَانِيدَ حَسَنَةٍ

On the authority of Abu al-'Abbas Sahl bin Sa'd al-Sa'idi, radiyallahu 'anhu, who said: A man came to the Prophet, sallallahu 'alayhi wasallam, and said: "O Messenger of Allah, direct me to an act which if I do it, [will cause] Allah to love me and people to love me." He, sallallahu 'alayhi wasallam, answered: "Be indifferent to the world and Allah will love you; be indifferent to what people possess and they will love you."
