415.Said the Prophet, (peace be upon him): 'On the Day of Resurrection, three people will find themselves on the ridge of black musk. They will have no reckoning to fear, nor any cause for alarm while human accounts are being settled. First, a man who recites the Quran to please Allah, Great and Glorious is He, and who leads the Prayer to people's satisfaction. Second, a man who gives the Call to Prayer in a Mosque, inviting people to Allah, Great and Glorious is He, for the sake of His good pleasure. Third, a man who has a hard time making a living in this world, yet is not distracted from the work of the Hereafter.' (Tirmidhi).
