While Ayyūb (peace be upon him) was taking a bath, naked, golden locusts began to fall upon him
Authentic hadithعن أبي هريرة رضي الله عنه عن النبي صلى الله عليه وسلم : "بينا أيوبُ -عليه السلام- يَغتَسلُ عُرياناً، فَخَرَّ عليه جَرَادٌ من ذَهَبٍ، فجعلَ أيوبُ يَحْثِي في ثوبِهِ، فنَاداه ربُّه عز وجل : يا أيوبُ، ألَمْ أكنْ أغْنَيتك عما تَرى؟!، قال: بلى وعزتِك، ولكن لا غِنى بي عن بركتِكَ".
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "While Ayyūb (peace be upon him) was taking a bath, naked, golden locusts began to fall on him. Ayyūb started collecting them in his clothes. His Lord, Glorified and Exalted, called him: 'O Ayyūb, have I not made you rich enough not to be in need of this?' Ayyūb replied: 'Yes, by Your might, but I cannot dispense with Your blessing.'"
Explanation
While Prophet Ayyūb (peace be upon him) was taking a bath naked, numerous pieces of gold, in the form of locusts, fell on him. Ayyūb (peace be upon him) kept collecting them and putting them in his clothes. Thereupon, his Lord, Glorified and Exalted, called him, saying: Have I not made you rich enough not to be in need of this? He replied: Yes, by Your glory. Yet, I have not taken this out of avarice or greed for this worldly life; but because they are a blessing from You.
