Allamah Abu Barakat Nasafi in Manar outlines five approaches to clarify statement: affirm (taqrir), explain (tafsir), modify (taghyir), imply (darurat) and replace (tabdil). Here we present Allamah Nasafi's explanation of necessary clarification whereby he outlines when an implied non-uttered thought will be treated as an uttered statement. Allm. Nasafi writes:
أو بيان ضرورة وهونوع بيان يقع بما لم يوضع له
وهو إما أن يكون في حكم المنطوق كقوله تعالي وورثه أبواه فلامه الثلث --
أو ثبت بدلالة حال المتكلم كسكوت صاحب الشرع عند أمر يعاينه عن التغيير --
أو ثبت ضرورة دفع الغرور كسكوت المولي حين رأي عبده يبيع ويشتري --
أو ثبت ضرورة كثرة الكلام كقوله عليّ مائة ودرهم --
Clarification by way of necessity is a type of clarification which occurs on aspects which are not [normally] specified. 1
[The unstated clarification] may be deemed to be equivalent to that which is uttered. For instance, Allah stating, 'Both the parents will inherit and for the mother is a third'2 .
[The unstated clarification] may be proven by the state of the speaker. For example the silence of the lawgiver3 on a matter in their presence [which entails] modification [of their statement or rule].4
[The unstated clarification] may be proven due to the need to remove misunderstanding. For example, the silence of the master when he sees his slaving buying and selling. 5
[The unstated clarification] may be proven due to the need [to minimise] excessive speech. For example, the statement, 'I owe a hundred and a dirham'.6
