People are under the impression that a man is perfectly pious when he fulfills the ritual obligations of Salaat, Saum, Hajj, Zakaat and dealings. This idea is incorrect. A man of perfect piety is one whose Zaahir and Baatin are reformed and adorned. There are many so-called deendaar (religious) persons
According to Durr-e-Mukhtaar the six fasts of Shawwaal may be incorporated with Qadhaa fasts (to acquire their thawaab as well). But this is incorrect. Tadaakhul (or incorporation of two different acts of ibaadat) will be proper if the purpose of both could be achieved by the incorporation, e.g. Tahayatul Musjid.
