[Machine] "Ali, may Allah be pleased with him, said: 'Learn knowledge, and when you have learned it, keep it to yourself, and do not mix it with laughter or play, for it will corrupt the hearts.'"
عَلِيٌّ رِضْوَانُ اللَّهِ عَلَيْهِ «تَعَلَّمُوا الْعِلْمَ فَإِذَا عَلِمْتُمُوهُ فَاكْظِمُوا عليْهِ وَلَا تَشُوبُوهُ بِضَحِكٍ وَلَا بِلَعِبٍ فَتَمُجَّهُ الْقُلُوبُ»
