سورة البلد

Imam Baqir (peace be upon him): وَ لِساناً [and a tongue] means Amir al-Mu'minin (peace be upon him); وَ شَفَتَیْنِ [and two lips] — Imam Hasan and Imam Husayn (peace be upon them).

Imam Sajjad (peace be upon him): Fear Allah! Your Lord has established His argument against you and has said: أَ لَمْ نَجْعَلْ لَهُ عَیْنَیْنِ* وَ لِساناً وَ شَفَتَیْنِ* وَ هَدَیْناهُ النَّجْدَیْنِ [Have We not made for him two eyes, and a tongue and two lips, and pointed out to him the two conspicuous ways?], and this is a proof against you.
