Sahih Muslim 7515

سِرْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي غَزْوَةِ بَطْنِ بُوَاطٍ وَهُوَ يَطْلُبُ الْمَجْدِيَّ بْنَ عَمْرٍو الْجُهَنِيَّ وَكَانَ النَّاضِحُ يَعْقُبُهُ مِنَّا الْخَمْسَةُ وَالسِّتَّةُ وَالسَّبْعَةُ فَدَارَتْ عُقْبَةُ رَجُلٍ مِنْ الْأَنْصَارِ عَلَى نَاضِحٍ لَهُ فَأَنَاخَهُ فَرَكِبَهُ ثُمَّ بَعَثَهُ فَتَلَدَّنَ عَلَيْهِ بَعْضَ التَّلَدُّنِ فَقَالَ لَهُ شَأْ لَعَنَكَ اللَّهُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ هَذَا اللَّاعِنُ بَعِيرَهُ قَالَ أَنَا يَا رَسُولَ اللَّهِ قَالَ انْزِلْ عَنْهُ فَلَا تَصْحَبْنَا بِمَلْعُونٍ لَا تَدْعُوا عَلَى أَنْفُسِكُمْ وَلَا تَدْعُوا عَلَى أَوْلَادِكُمْ وَلَا تَدْعُوا عَلَى أَمْوَالِكُمْ لَا تُوَافِقُوا مِنْ اللَّهِ سَاعَةً يُسْأَلُ فِيهَا عَطَاءٌ فَيَسْتَجِيبُ لَكُمْ

It is reported on the same authority: We set out along with Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) on an expedition of Batn Buwat. He (the Holy Prophet) was in search of al-Majdi b. 'Amr al-Juhani. (We had so meagre equipment) that five. six or seven of us had one camel to ride and so we mounted it turn by turn. Once there wan. the turn of an Ansari to ride upon the camel. He made it kneel down to ride over it (and after having. mounted it), he tried to raise it up but it hesitated. So he said. May there be curse of Allah upon you! Thereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: Who is there to curse his camel? He said: Allah's Messenger, it' is I. Thereupon he said: Get down from the camel and let us not have in our company the cursed one. Don't curse your own selves, nor your children. nor your belongings. There is the possibility that your curse may synchronies with the time when Allah is about to confer upon you what you demand and thus your prayer may be readily responded.
