When he is left with a crooked neck: what is due for it?

It is narrated from Sayyiduna Zayd (may Allah be pleased with him): For a crookedness of the neck or face toward one side of the jaw, there is blood money (diyah).

Ibn Jurayj said: Abd al-Aziz bin Umar informed me that the commanders of the armies agreed, for Umar bin Abd al-Aziz, on this: When the crookedness is such that the man cannot turn toward the other side, from which his face has been turned, there are fifty dinars.
