Water is due to water

It was narrated from Abu Sa'eed Al-Khudri that:
The Messenger of Allah passed by (the house of) one of the Ansar and sent word for him to come out. He came out with his head dripping and (the Prophet) said: "Perhaps we made you hurry?"He said: "O Messenger of Allah." He said, "If you are hurried (by someone) or obstructed (from orgasm) and do not ejaculate, then you do not have to take a bath, but you should perform ablution."

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا غُنْدَرٌ، مُحَمَّدُ بْنُ جَعْفَرٍ عَنْ شُعْبَةَ، عَنِ الْحَكَمِ، عَنْ ذَكْوَانَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، أَنَّ رَسُولَ اللَّهِ ﷺ مَرَّ عَلَى رَجُلٍ مِنَ الأَنْصَارِ فَأَرْسَلَ إِلَيْهِ فَخَرَجَ رَأْسُهُ يَقْطُرُ فَقَالَ " لَعَلَّنَا أَعْجَلْنَاكَ " . قَالَ نَعَمْ يَا رَسُولَ اللَّهِ . قَالَ " إِذَا أُعْجِلْتَ أَوْ أُقْحِطْتَ فَلاَ غُسْلَ عَلَيْكَ وَعَلَيْكَ الْوُضُوءُ " .
