The origin of "Tasāmuḥ" in the Arabic language is the root سمح, which means fluidity and simplicity, as mentioned by the great Persian philologist and lexicographer Aḥmad Ibn Fāris. While as a technical term the "Tasāmuḥ" is generally used for two meanings:
After remembering the meaning of the word "Tasāmuḥ" both as language and as a technical term, “Al-Iṣṭilāḥ”, we will try to address this pious characteristic in synthesis, based on Quranic passages, on the prophetic Sunna and on the declarations of the wise men. We all know the best story told in the Holy Quran about the prophet Yusuf عليه السلام and the seal of the prophets, Moḥammad ﷺ Yusuf عليه السلام envied by his brothers, seeing the love and prestige he had in the eyes of his father and prophet, Jacob عليه السلام, pushed the jealous brothers to make a decision. There are those who wanted to get rid of him once and for all by urging them to kill him. Others instead advised to throw him out into a well. Allah ﷻ said about their trap: “When they said, “Yusuf and his brother are dearer to our father, even though we are a capable group. Indeed our father is in blatant error. Kill Yusuf, or abandon him in some land, so that your father's face does not turn to anyone but you, after which you will be well considered. One of them spoke up and said, Do not kill Joseph. If you really have decided, throw him rather at the bottom of the tank, so that some caravan can find him »”. (Quran 12:8)
The final decision was precisely to throw him down from a well, yet after years of trials and sufferings he became by destiny of God, the Minister of Economy of Egypt. The Lord brought the brothers who threw him without sense of reserve up to him, they recognized him saying: “Are you really Yusuf”? He replied: “I am Yusuf and this is my brother”. Yusuf عليه السلام could at that moment lead them to the worst punishment, given his position, but for fear of God he preferred forgiveness, the "Tasāmuḥ", in fact he told them as mentioned in the Quran: "Today you will not suffer any reproach! May Allah forgive you, He is the most merciful of the merciful ». (Quran 12:92)
Stesse parole le disse il sigillo dei Profeti, Moḥammad ﷺ, “oggi non subirete alcun rimprovero! Che Allah vi perdoni”. Disse queste saggie parole quando conquistò la Mecca, attorno a lui c’erano i compagni e gli abitanti della sua tribù Quraish, spaventati dalla grande forza religiosa che in pochi anni era riuscita ad espandersi e dal profeta che avevano davanti, colui che cambiò le pessime consuetudini a cui gli arabi erano abituati, in una purezza divina, il nobile Corano, che diede i diritti a donne, bambini, ricchi, poveri, tutti sullo stesso livello, rendendo il migliore di loro il più timorato di Allah ﷻ Il profeta ﷺ vide negli occhi di coloro che lo avevano cacciato dalla Mecca, insultato, sbugiardito un senso di terrore e vergogna, a quel punto disse: “ O gente di Quraish, cosa pensate faccia di voi”? Risposero: “Del bene, fratello generoso, figlio di un fratello generoso”!! Rispose a loro il profeta della misericordia: «Dico a voi ciò che ha detto Giuseppe ai suo fratelli, oggi non subirete alcun rimprovero! Che Allah vi perdoni».
We note in these two examples reported by two great prophets, Yusuf and Moḥammad peace and blessing be upon them, that like forgiveness, the "Tasāmuḥ" can be considered as a general rule, a principle on which being human must be based, the believer above all. This characteristic which is a sign of an elevated character and a big heart, the one who on the day of Judgment wants to arrive with a pure heart, cannot fail to have the "Tasāmuḥ" as a characteristic. It is precisely this that prompted the second caliph Abu Bakr to forgive and continue to do charity to Miṣṭaḥ, despite having slandered his daughter 'Aisha, who was found innocent by the Creator of the worlds. This was the character of the prophet ﷺ, as the mother of the believers' Aisha told us, may Allah be pleased with her: "The prophet was neither obscene, nor did he utter obscenities, he did not shout in the markets, he did not return the evil suffered with the same evil, but he graced and forgave ”. We conclude by mentioning some poetic verses reported by the great jurist al-Shāfi'i: Attend with good ways and forgive the aggressor Repel violence with something better We are at the gates of the best month of the year, we try to erase all wounds, forgiving and valuing each person so that Allah values us and opens the doors of his mercy to us, as the prophet ﷺ says; “have mercy on those who are on Earth and will have mercy of you He who is above the heavens”.
“O our Lord do not let our hearts get lost after you have guided them and grant us mercy on your part, in truth you are the one who gives. O Allah, we have failed against us, if you do not forgive us and have mercy on us, we will certainly be among the losers, Lord forgive us and our brothers who preceded us in faith, and do not place in our hearts any grudges towards believers, Our Lord You are sweet and merciful. O our Lord, You who are the Forgiver and love forgiveness, forgive us”.
