People praying voluntary prayer in a corner

Ibrahim says that those devoted to night prayer (al-mutahajjidun) used to pray in one corner of the mosque while the imam was leading the people in the tarawih.

Ayyub says: I saw Ibn Abi Mulaykah leading the people in the tarawih prayer behind the Station of Ibrahim, while the people throughout the rest of the mosque were some circling the House (in tawaf) and some praying.

Ash'ath bin Abi al-Sha'tha' says: I was in Makkah in Ramadan in the time of Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with him), and I saw the imam leading a group separately in the tarawih while people were offering their own prayers in the corners of the mosque.

Abd al-Malik bin Umayr says: I saw Shabath bin Rib'i and some people with him praying individually in Ramadan while the (other) people were in the congregational prayer. And I saw Shabath praying alone facing a sutrah.

Ibrahim says that the imam would be leading the people in the tarawih in the mosque, while those devoted to night prayer (al-mutahajjidun) would be offering their own prayers in the corners of the mosque.
