Is it permissible to add to the composed supplications?

Question : Adding to the composed supplications.

Answer : Adding to the composed supplications: if these supplications have no meaning, or if their meaning is perhaps distorted, such as "We have tethered our camels at your door, so do not distance me from your presence; if you do distance me, there is no power and no strength except in You," then there is no doubt that this is at the least disliked. If the rhyming contains nothing prohibited, but the person prolongs it until it becomes burdensome for the people, then it is forbidden, because the Prophet (peace and blessings be upon him) became angry with Mu'adh ibn Jabal when he prolonged the prayer for the people. However, if the number of people is limited, and they said, "O so-and-so, prolong the supplication for us," then if the number is limited, such as if they are the people of a farm in a limited mosque, and they said to their imam, "Prolong the supplication for us," then there is no harm in that.
