The Shaykh’s explanation of wisdom in calling to Allah? And examples of that?

The Shaykh : But here, on this occasion, it is necessary to mention a condition. It must be accompanied by the thought and action of the one who enjoins good and forbids evil, and that is that his enjoining of good and forbidding of evil must be done with what is good, that his enjoining of good and forbidding of evil be done with the good manners of the Shari'ah. We all know the saying of our Lord, Blessed and Exalted is He, in the Noble Qur'an: . The first thing that comes to our minds, and to the minds of others, regarding wisdom here is gentleness and leaving off harshness and severity, as the Exalted said: . This is a matter observed in the guidance of the Messenger of Allah (peace and blessings be upon him) and in his practical Sunnah. He was merciful and compassionate to his Ummah, as our Lord, Blessed and Exalted is He, described him in the Noble Qur'an: . He (peace and blessings be upon him) was thus in his lifestyle and in his teaching of his Ummah. Perhaps all of you present, we all know the story of that Bedouin who appears to have been a recent convert to Islam and had not yet learned the Islamic etiquettes and the rulings of the Shari'ah. He tried to urinate in the Prophet's Mosque. You know that the Prophet's Mosque was paved with gravel. When his Companions (may Allah be pleased with them) saw him doing this, they were about to strike him, but the Messenger of Allah (peace and blessings be upon him) said to them: , meaning do not stop his urination. . He (peace and blessings be upon him) left him to urinate until he was relieved. But the man, to the extent that he was pleased with the gentleness of the Messenger of Allah (peace and blessings be upon him) toward him, was angered by the harshness of his Companions. This appeared in his supplication after the prayer, where he said: "O Allah, have mercy on me and on Muhammad, and do not associate anyone with us in that. O Allah, have mercy on me and on Muhammad, and do not associate anyone with us in that." Muhammad deserves mercy because he is merciful, but these rough, hard-hearted people do not deserve mercy. "O Allah, have mercy on me and on Muhammad, and do not associate anyone with us in that." So the Messenger of Allah (peace and blessings be upon him) returned to teach him, saying to him: . "You have restricted" means you have narrowed a vast expanse of the mercy of Allah, Blessed and Exalted is He. This is one of the gentle, soft methods of the Messenger of Allah (peace and blessings be upon him) in disciplining his Companions and in enjoining good and forbidding evil.
But there is a story similar to this, which many people may not know. It is the story of that Companion who spoke during the prayer, and those around him tried to silence him by striking their thighs. He is known as what? Mu'awiyah ibn al-Hakam al-Sulami. This Mu'awiyah is not Mu'awiyah ibn Abi Sufyan, who later became the Caliph of the Muslims. Mu'awiyah ibn al-Hakam al-Sulami himself says: "I prayed one day behind the Prophet (peace and blessings be upon him). A man next to me sneezed, so I said to him, 'May Allah have mercy on you.' He looked at me—meaning a look that silenced those around him—and they were distressed by it. He called out at the top of his voice: 'Wathukhli ummiyay' (May my mother be bereaved of me). He was praying and calling out at the top of his voice: 'Wathukhli ummiyay'—meaning my mother has lost me—cursing himself. Why are you looking at me? What is wrong with you that you are looking at me? So they began striking their thighs. Be quiet now, this is not a time for talking. He said—and here is the point—: to the end of the hadith. The hadith is long, and although it contains benefits, we will not prolong it for you now.
The point is that the man felt he had made a mistake in the prayer from the looks of the Companions at him, looks of disapproval in the prayer, and then from their striking their thighs to silence him. He knew that he had been wrong. Someone like him would imagine and tell himself: Now, I wonder, after the prayer, what will the Messenger of Allah (peace and blessings be upon him) punish me for this mistake I committed? So he answers himself with himself, and says: . I say that enjoining good must be done with what is good. But here is the thing that one should be aware of and be alerted to: sometimes it is necessary to use severity, because the Prophet (peace and blessings be upon him) ...
