On Ibn Malik’s saying, “... As for you, if you are righteous, then draw near...”

The Shaykh : In any case, if someone holds that it is conditional, that is undoubtedly better, meaning it is closer to these three or four operations. Yes, the important thing is that this is an easy operation. As for “if you are righteous, then draw near,” and its counterpart: “As for if you are not righteous, do not draw near,” the “fa” here occurs in the answer to the condition. As for those who say it is a substitute for “kana,” they say the “fa” came here because the cause resembles a condition; so when the cause resembled a condition, it became permissible for the “fa” to be in its answer. This is also a cause that weakens the estimation they mentioned regarding what was substituted for “kana.” Good, the fourth characteristic.
