13- ḥadīth (333) I had mentioned to him there three chains from Thawr ibn Yazīd from Khālid ibn Maʿdān from Abū Hurayrah. Then I found a fourth chain for it, narrated by ʿĪsá ibn Yūnus—who is the son of Abū Isḥāq al-Sabīʿī—from Thawr ibn Yazīd with it. It was recorded by Ibn al-Sunnī in "ʿAmal al-Yawm wa-al-Laylah" (56/157) through the chain of Sulaymān ibn ʿUmar ibn Khālid, and by al-Ṭabarānī in "Musnad al-Shāmiyyīn" (1/241) (no. 429) through the chain of ʿAmr ibn Khālid al-Ḥarrānī, both saying: ʿĪsá ibn Yūnus narrated it with it. And this isnād is authentic. (Benefit): His saying (ṣallá Allāhu ʿalayhi wa-sallam) after mentioning some shares of Islam after faith in Allāh, like prayer and zakāh: "Whoever abandons any of that has abandoned a share of Islam, and whoever abandons all of them has turned his back on Islam." I say: This is an explicit text that a Muslim does not leave Islam by abandoning some of its shares, including prayer. The one who abandons is merely a sinner whose testimony is not accepted, and it is feared for him a bad end. This has been detailed in a discussion on the ruling of abandoning prayer under ḥadīth (87), which is conclusive evidence for what we mentioned. Therefore, some have tried to evade its implication by attempting to weaken it, but in vain. We have refuted that with evidence and proof, and clarified who among the scholars of Islam has authenticated it, so refer to it
