Al-Mofaddal Bin Amr reported from Imam Jaafar Bin Mohammad Al-Sadiq (pbut) that he said: "You must comport yourself with honorable deeds, for Allah Almighty indeed loves them and dare not do disgraceful deeds, for Allah Almighty indeed detests them. You must as well recite the Quran, for the ranks of Heaven are equal to the number of its verses. Thus on the Day of Resurrection, the reciter of the Quran will be told: "Recite and rise." Therefore, he rises to a higher rank for each verse he reads. You must also have good manners, for it allows its doer to reach the rank of those who fast and pray greatly. Moreover, you must be a good neighbor, for Allah ordered it. You must use the Miswak, for it is purifying and it is a good tradition. You must carry out what Allah orders and avoid what He forbids.
