Taraaweeh should be performed with Jamaa’t if this is possible. If a Haafiz wishes to perform 20 raka’ts at home, then he should ask at least one or two others to join him. If there are no males, then he should perform Jamaa’t with his wife and children.But the Isha’ Fardh should be performed at the Musjid. If he is unable to find anyone to join him, he may perform 20 raka’ats alone at home.
