Offering a New Concept of the Lutf Rule and Its Necessity in AyatullahSubhani's Works

Based on the basis that sending the prophets is one of the cases for Lutf al-muqarreb, the majority of the previous Mutakallemun proved the necessity of sending the prophets by the Lutf rule. From Allah al-Hilli in Kashful- Murad, some grasped that sending the prophets is not a case for the Lutf rule. Thus, from their opinion, the Lutf rule is no longer useable for proving the necessity of prophet-hood. In the other hand, from Sheik al-Mufid upwards, another theory had been current that Lutf is not rationally necessary, and as a result, its effectiveness in proving the belief issues has been challenged. To resolve this problem, AyatullahSubhani separated between the cases. He maintains that Luft al-Muqarreb in some cases is rationally necessary and in some other cases is notnecessary, but is a demand of God's grace and bestow. In present article, the above mentioned discussions are examined in the AyatullahSubhani's works and its success and failure extents are evaluated.
