Is the Hadith, "He who performs ghusl and bathes (or makes his wife bathe)," specific to married couples, or does it refer to performing ghusl with the intention of purification (ghusl janabah)? What is the extent of the early arrival intended in this Hadith and the other Hadith that elaborates on the reward for the first hours? And what is the exact time for entering the mosque to attain the reward of the first hour?

The hadith (definition) "Man ghasala wa-aghtasala" (Whoever washes and is washed) is authentic. The predominant narration among verifying scholars is with the lightened 'sin' (ghasala), meaning he washed his head. This is because they used to apply oil and henna to their hair, so they would wash it first and then perform the full bath. The virtue of early arrival for Jumu'ah is achieved by being present in the mosque before the Imam ascends the pulpit. The earlier one arrives, the greater the reward, and early arrival begins from sunrise.
