Is standing [during] the last third [of the night in prayer] best? [Please advise] with clarity of the time when the last third of the night is.
Asad ibn ‘Amr said that for forty years, Abu Haneefah prayed the ‘Ishaa [prayer] and the morning (Fajr) prayer with [the same] wudhoo.
His set portion [of worship] every night was [to pray] twenty rak’ahs whilst at home and [also when on] travels. And when he would be done with them, he would write thirty five pages of his book.
I hosted Abu Hurayrah for seven days; he, his wife and his servant would divide the night into thirds, [whereby] he would pray, then wake up the other who would then pray, and then wake up the other [who would then also pray].
If you are unable to establish the [voluntary] night prayer, nor [voluntarily] fast during the day, then know that you have been prevented [from doing these great acts of worship], because you have been shackled by your sins.
