Does the obligatory prayer suffice for the two rak'ahs of tawaf?

Question : The question is whether the intention for the two rak'ahs of tawaf overlaps with the intention for the rawatib prayer. That is, a man performed tawaf after the adhan for the midday prayer, finished the tawaf, and wanted to pray two rak'ahs behind the Maqam. He intended them to count for the two rak'ahs of tawaf and for the rawatib of the midday prayer. Does that suffice, or must he pray a separate prayer for each?

Answer : He says: If we hold that the two rak'ahs of tawaf are obligatory, then the rawatib does not suffice for them, because a recommended practice does not suffice for an obligatory act. If we hold that they are not obligatory, then it suffices. However, there is another distinction: if we say that the Lawgiver has a specific purpose for two independent rak'ahs behind the Maqam, then they do not suffice for the rawatib, because the rawatib is also intended for its own sake. In that case, one must pray two rak'ahs behind the Maqam and the rawatib prayer. If we say that the Lawgiver merely prescribed praying two rak'ahs, regardless of whether they are for the Maqam or for anything else, then we say it suffices. The view that is stronger in my opinion is that two rak'ahs are required for each: two rak'ahs for the rawatib, and two rak'ahs for the prayer behind the Maqam.
