11. Al-Husayn ibn Muhammad has narrated from Mu’alla ibn Muhammad from al- Hassan ibn Ali al-Washsha’ from ‘Umar ibn Aban from abu Basir who has said the following: “I heard Abu ‘Abdillah saying, ‘The Messenger of Allah has said, “Tuba’ (a tree in paradise) is for a servant who is unknown to people but Allah knows him. Such people are the torches of guidance and the fountains of knowledge. Through them every darkening calamity brightens. They do not publicize undisclosed facts and they are not quarrelsome braggarts.’”
