Hadith of Golden Chain al-Bayt, hence called "Hadith of Golden Chain". Several Important hadith collections quoted it as "Al-Tawhid", "Ma'ani al-Akhbar", and Oyoun Akhbar Al-Ridha of al-Shaykh al-Saduq and Al-Amali of Shaykh Tusi. The hadith is also narrated in sunni hadith books. Regarding the implications of the hadith, there are two extreme opinions by Sunni scholars; While some of them discrediting the hadith by implying that the Sunni books lack it, some others claim that all Sunni scholars accepted it. According to shia, two important points may be derived from the Hadith. On one hand, monotheism takes the believers to "Allah's fortress", which is
Slice genus of "K" is 1 while the genus and the smooth slice genus of "K" both equal g. The (smooth) slice genus of a knot "K" is bounded below by a quantity involving the Thurston–Bennequin invariant of "K": The (smooth) slice genus is zero if and only if the knot is concordant to the unknot. Slice genus In mathematics, the slice genus of a smooth knot "K" in "S" (sometimes called its Murasugi genus or 4-ball genus) is the least integer g such that "K" is the boundary of a connected, orientable 2-manifold "S" of genus "g" properly embedded in the
