Q193: Is it permissible to ask for sustenance, a child, protection or intercession directly from the infallible ones?
Follow up: Let me ask you first. Do you seek this from them because they create, or sustain, or protect?
Response: Certainly not. But rather because they are the means to Allah (s.w.t.), the intercessors with Him in the disposal of affairs, and because they cannot do anything but with the permission of Allah, the Sublime and Exalted.
Follow up: You mean that they ask Allah the Exalted and He creates, and they ask Him and He sustains, and they ask Him and He protects, and because they are intercessors, whose pleas or supplications are not rejected, because of their status with Allah, the Sublime, and for their guardianship over us?
Response: Yes, I mean that.
A: This is permissible. Allah (s.w.t.) says: "...and seek means of nearness to Him..." (Qur'an, 5:35) and they (a.s.) are your means of approach to Allah (s.w.t.). This is permissible. (FM, p. 421)
