Q 6: Hadith have been reported including that narrated by Ibn `Umar (may Allah be pleased with both) who said, I memorized (a tradition of) ten Rak`ahs (units of prayer) of Nawafil (supererogatory prayers) from the Prophet (peace be upon him): two Rak`ahs before Zhuhr (Noon) Prayer and two after it; two Rak`ahs after Maghrib (Sunset) Prayer in his house, and two Rak`ahs after `Isha' (Night) Prayer in his house, and two Rak`ahs before Fajr (Dawn) Prayer. Related by Al-Bukhari. It is also narrated on the authority of Um Habibah bint Abu Sufyan that the Prophet (peace be upon him) stated, Whoever prays twelve Rak`ahs of prayer voluntarily in a day and night, Allah will build him a house in Jannah (Paradise). These twelve Rak`ahs are: Four Rak`ahs before the Zhuhr (Noon) Prayer and two Rak`ahs after it, two Rak`ahs after Magrib (Sunset) Prayer, two Rak`ahs after `Isha (Night) Prayer and two Rak`ahs before the Fajr (Dawn) Prayer. Related by Al-Tirmidhy, and he said: This is a Hasan (sound) and authentic Hadith.Are the two Rak`ahs of Tahiyyat-ul-Masjid included among the Rak`ahs mentioned in the two Hadith? Do the two supererogatory Rak`ahs after `Isha' Prayer the two Shaf` Rak`ahs (two units of Prayer, particularly before the final unit of the odd-number prayer)?
