Narrated Anas bin Malik:

That when Haram bin Milhan, his uncle was stabbed on the day of Bir Ma'una he sprinkled his blood over his face and his head this way and then said, "I have succeeded, by the Lord of the Ka`ba.'

حَدَّثَنِي حِبَّانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، قَالَ حَدَّثَنِي ثُمَامَةُ بْنُ عَبْدِ اللَّهِ بْنِ أَنَسٍ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ يَقُولُ لَمَّا طُعِنَ حَرَامُ بْنُ مِلْحَانَ ـ وَكَانَ خَالَهُ ـ يَوْمَ بِئْرِ مَعُونَةَ قَالَ بِالدَّمِ هَكَذَا، فَنَضَحَهُ عَلَى وَجْهِهِ وَرَأْسِهِ، ثُمَّ قَالَ فُزْتُ وَرَبِّ الْكَعْبَةِ‏.‏
