To what extent are the sayings and rumors circulating about the integrity of Sheikh Muhammad Metwally Al-Sha'rawi, which advise against him, true?

"Proper conduct with scholars and respecting them is obligatory, for they are the inheritors of the prophets. Treating them lightly can lead to loss in the Hereafter. Sheikh Al-Shaarawi served Islam and defended the religion. Like any other human being, he made mistakes and was correct at times. Whatever he said that aligned with the truth is to be accepted, and whatever he erred in was his ijtihad, for which he may be rewarded."
