Hadith 1:167
Isnād Da'īf (Zubair `Aliza'i)
Anas reported God’s messenger as saying, “Sonny, if you can keep your heart morning and evening void of deceit towards anyone, do so.” Then he said, “Sonny, that pertains to my sunna . He who loves my sunna has loved me, and he who loves me will be with me in paradise.” Tirmidhi transmitted it.
وَعَن أنس قَالَ: قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَا بُنَيَّ إِنْ قَدَرْتَ أَنْ تصبح وتمسي لَيْسَ فِي قَلْبِكَ غِشٌّ لِأَحَدٍ فَافْعَلْ» ثُمَّ قَالَ: «يَا بني وَذَلِكَ من سنتي وَمن أَحْيَا سُنَّتِي فَقَدْ أَحَبَّنِي وَمَنْ أَحَبَّنِي كَانَ مَعِي فِي الْجنَّة» . رَوَاهُ التِّرْمِذِيّ
