It is recommended for the fasting person to use the siwak during the day of Ramadan, and it is the same at the end of the day as it is at the beginning, even if it is wet or moistened with water; because the amount of water is not enough to remain in the mouth from the moisture after rinsing. However, some preferred to spit after rinsing even once. See: Al-Badai 2: 106, and Al-Hadiya p. 171; For it was narrated by Amir ibn Rabi'ah, may Allah be pleased with him, that he said: ((I saw the Prophet, peace be upon him, using the siwak while he was fasting)) in Al-Jami' Al-Tirmidhi 3: 104, and he graded it as good, and in Sunan Al-Daraqutni 2: 202, and Musnad Ahmad 3: 445, and Al-Ahadith Al-Mukhtara 8: 182. And from Aisha, may Allah be pleased with her, the Prophet, peace be upon him, said: ((One of the best characteristics of the fasting person is the siwak)) in Sunan Ibn Majah 1: 536, and Sunan Al-Bayhaqi Al-Kabir 4: 272, and Sunan Al-Daraqutni 2: 203, and Al-Suyuti symbolized it as good in Al-Jami' Al-Saghir 3: 486; as he described using the siwak as good in general without distinguishing between the wet and the dry, and whether it is at the beginning or the end of the day; because the purpose of it is to purify the mouth, so the wet and the dry are equal in this regard at the beginning and end of the day: like rinsing. And from Abdul Rahman ibn Ghanm, may Allah be pleased with him, he said: I asked Mu'adh ibn Jabal, may Allah be pleased with him, do you use the siwak while you are fasting? He said: Yes. I said: When during the day do you use it? He said: Whenever during the day you wish, whether in the morning or in the evening. I said: But people dislike it in the evening. He said: Why? I said: They say that the Messenger of Allah, peace be upon him, said: ((The breath of the fasting person is sweeter to Allah than the scent of musk)). He said: Glory be to Allah, the Messenger of Allah, peace be upon him, commanded them to use the siwak when he commanded them, and he knew that there must be a bad smell in the mouth of the fasting person even if he used the siwak, and he would not command them to deliberately make their mouths stink, for there is nothing good in that, rather it is evil. In Al-Mu'jam Al-Kabir 20: 70, Ibn Hajar said in Takhlees Al-Habeer 2: 202: Its chain of narration is good. See: Badai Al-Sanai 2: 106.
