Hadith of Golden Chain Hadith of Golden Chain Hadith al-Silsilah al-Dhahab () (Hadith of the Golden Chain) is a hadith narrated from Ali al-Ridha, the eighth Imam of the Shia. The "chain" is a reference to the continuity of spiritual authority which is passed down from Muhammad to Ali ibn Abi Talib, through each of the Imams, to Imam Ridha. As transmitters of Hadith, the Imams link subsequent generations to the teachings of Mohammad. This transmission makes the Hadith of the Golden Chain valued as among the most truthful and accurate of all Hadiths for the Shi'ite. The hadith is important to shia because
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
