عَنْ طَلْقِ بْنِ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ: وَفَدْنَا عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَلَمَّا وَدَّعَنَا أَمَرَنِي فَأَتَيْتُهُ بِإِدَاوَةٍ مِنْ مَاءٍ فَحَثَا مِنْهَا ثُمَّ مَجَّ فِيهَا ثَلَاثًا ثُمَّ أَوْكَأَهَا ثُمَّ قَالَ: ((اذْهَبْ بِهَا وَانْضَحْ مَسْجِدَ قَوْمِكَ وَأْمُرْهُمْ أَنْ يَرْفَعُوا بِرُؤُوسِهِمْ أَنْ رَفَعَهَا اللَّهُ)) قُلْتُ: إِنَّ الْأَرْضَ بَيْنَنَا وَبَيْنَكَ بَعِيدَةٌ وَإِنَّهَا تَيْبَسُ، قَالَ: ((فَإِذَا يَبِسَتْ فَمُدَّهَا))
Sayyiduna Taliq bin Ali (may Allah be pleased with him) says that we came to the Noble Prophet (peace and blessings be upon him) as a delegation. When the Prophet (peace and blessings be upon him) bade us farewell, he instructed me, so I brought a water jug to him. He took a handful from it and rinsed his mouth three times, then tied it with a strap and said: Take this water and sprinkle it on the mosque of your people, and instruct the people to now raise their heads, for Allah Almighty has raised them. Sayyiduna Taliq bin Ali (may Allah be pleased with him) said: The distance between us and you is very great, so this water will dry up. (Upon hearing this) the Prophet (peace and blessings be upon him) said: When it begins to dry up, (add more water to it and) increase it.
