Hadith: If I had gold equal to the mountain of Uhud, it would please me that I should have nothing left of it with me after the passage of three nights, except what I might retain to repay a debt

عَن أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ: قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:

«لَوْ كَانَ لِي مِثْلُ أُحُدٍ ذَهَبًا مَا يَسُرُّنِي أَنْ لاَ يَمُرَّ عَلَيَّ ثَلاَثٌ، وَعِنْدِي مِنْهُ شَيْءٌ إِلَّا شَيْءٌ أُرْصِدُهُ لِدَيْنٍ».
[صحيح] - [متفق عليه]

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "If I had gold equal to the mountain of Uhud, it would please me that I should have nothing left of it with me after the passage of three nights, except what I might retain to repay a debt."
Sahih/Authentic. - [Al-Bukhari and Muslim. This is the wording of Al-Bukhari]

Explanation

If I had a wealth of pure gold that is equal to the mountain of Uhud, I would spend all of it in the cause of Allah and would not keep anything thereof, expect what I need for fulfilling rights and repaying my debts.
