The letter of “سین” (seen) for emphasis in the Qur'an and the view of commentators and translators on it

In spite of its significant use in the Holy Qurʾān, the Sīn of emphasis is still strange and unknown, its uses are mainly attributed to the sin of taswif or Istiqbāl, and its precise and sensitive position is neglected. In this study, we assume that many cases of the use of the letter Sīn on the participle verb in the Qurʾān are for emphasis on the verb after itself; not to convey the meaning of waiting and delay. Based on this assumption, we will try to describe and analyze the opinions about the meaning of this letter in the verses of the Qurʾān by extracting the cases of the use of the letter Sīn in the Qurʾān and referring to various interpretations and books on the grammar and ʿUlūm al-Qurʾān and the famous Persian translations of the Qurʾān. We want to defend this hypothesis that many cases of the use of Sīn on the present participle in the Holy Qurʾān are not for delay and waiting - as most of the commentators and translators have imagined - but to indicate emphasis, and it should be done when Its translation is equivalent to words such as certainly, of course, in fact, undoubtedly, inevitably, inevitably, constantly, continuously etc.
