Wudu is not permissible with rose water, tree water, or safflower water; ritual purity is not permissible except with absolute water (ma' mutlaq) to which the name "water" applies. This is because ritual purity is only permissible with water, and this substance does not bear the name of "water" in an absolute sense.
The second category: That which has been mixed with a pure substance from which it is possible to refrain, such that it alters one of its attributes: its taste, color, or odor, such as the water of fava beans, chickpea water, and saffron water.
The scholars have disagreed regarding the permissibility of wudu with it, and there is a difference in narration from our Imam, may Allah have mercy on him, in this regard. It is narrated from him that ritual purity is not achieved by it. This is the view of Malik, al-Shafi'i, and Ishaq. Judge Abu Ya'la said: "This is more correct, and it is the supported view among our companions in the works of disagreement (al-khilaf)."
A group of his companions have transmitted from Ahmad, among them Abu al-Harith (42), al-Maymuni (43), and Ishaq bin Mansur (44), the permissibility of wudu with it. This is the school of Abu Hanifa and his companions, because Allah the Almighty said: {And if you do not find water, then perform tayammum} (45). This is general for all water, because it is an indefinite noun in a context of negation, and an indefinite noun in a context of negation implies generality. Therefore, tayammum is not permissible while it is present. Also, the statement of the Prophet, peace and blessings of Allah be upon him, in the hadith of Abu Dharr: "The soil is sufficient for you as long as you do not find water (46)." This person is a finder of water. Furthermore, the Prophet, peace and blessings of Allah be upon him, and his companions used to travel, and the majority of their water containers
