Does going early to the mosque five hours before the sermon or sleeping in the mosque before the sermon include its doer in the reward of the hadith, "Whoever washes and is washed..."?

Hasten to Jumu'ah begins from sunrise. The hours mentioned regarding the virtue of hastening are temporal portions calculated by dividing the time from sunrise until the Imam arrives into five equal parts, and they are not necessarily specific astronomical hours. The length of these portions varies with the seasons. As for sleeping in the mosque, it is permissible, and one is rewarded for it if the goal is to be able to listen attentively to the sermon. However, the essence of hastening is to await the prayer and engage in remembrance.
