It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whatever blessing Allah Almighty grants a servant in his family, wealth or children, and he says these words: 'Ma sha' Allah, la quwwata illa billah' (What Allah wills [is what happens]; there is no power except with the help of Allah), he will not see any calamity in that blessing short of death." And Sayyiduna Anas (may Allah be pleased with him) used to give this same interpretation of this verse: "And why, when you entered your garden, did you not say: What Allah wills [is what happens]; there is no power except with the help of Allah."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Anas (may Allah be pleased with him) only with this chain; Umar bin Yunus is alone in narrating it."
