Narrated Ibn 'Umar (RA):
I heard Allah's Messenger (ﷺ) say, "If you sell anything on credit to anyone, on the condition that you will buy it back for a lower price (al-'Einah), take hold of the tails of cattle, become pleased with agriculture and give up Jihad - Allah will make disgrace prevail over you and will not remove it from you till you return to your religion."

[Reported by Abu Dawud from the narration of Nafi' on the authority of Ibn 'Umar (RA), but there is a defect in its chain].
وَعَنِ اِبْنِ عُمَرَ ‏-رَضِيَ اَللَّهُ عَنْهُمَا‏- [قَالَ]: سَمِعْتُ رَسُولَ اَللَّهِ ‏- صلى الله عليه وسلم ‏-يَقُولُ: { إِذَا تَبَايَعْتُمْ بِالْعِينَةِ, وَأَخَذْتُمْ أَذْنَابَ اَلْبَقَرِ, وَرَضِيتُمْ بِالزَّرْعِ, وَتَرَكْتُمْ اَلْجِهَادَ, سَلَّطَ اَللَّهُ عَلَيْكُمْ ذُلًّا لَا يَنْزِعُهُ حَتَّى تَرْجِعُوا إِلَى دِينِكُمْ }  رَوَاهُ أَبُو دَاوُدَ مِنْ رِوَايَةِ نَافِعٍ عَنْهُ, وَفِي إِسْنَادِهِ مَقَالٌ.‏  1‏ .‏‏1 ‏- صحيح بطرقه رواه أبو داود ( 3462 )‏.‏
