What is our stance regarding the preacher who insulted the Companion Al-Aqra' ibn Habis and described him as "O madman" for objecting to the Prophet, peace and blessings be upon him, kissing his children?

Whoever says that Al-Aqra' ibn Habis, may Allah be pleased with him, was a disbeliever has erred, for all the Companions are trustworthy, and it is not permissible to revile them. Al-Aqra' was a venerable Companion who witnessed important battles such as Dumat al-Jandal and the Iraq War. He was a noble man in both pre-Islamic times and Islam. He was martyred at Yarmouk along with ten of his sons, which is a great virtue for him.
