Al-Matalib al-'Aliyah 143 — Wudu after sleep

It is narrated from Harmalah, the freed slave of Sayyiduna Zayd bin Thabit (may Allah be pleased with him): I asked Sayyiduna Zayd bin Thabit (may Allah be pleased with him) for a legal ruling about sleeping while sitting, and he saw no harm in it (that is, he did not consider it to break ablution). I said: What is your view if I lay my side on the ground (to sleep)? He said: "Then perform ablution."
In the chain of this narration, Muhammad bin Umar al-Waqidi and Ibn Abi Sabrah are matruk (abandoned) and severely da'if (weak) narrators; moreover, Asim bin Ubaydullah has also been declared da'if (weak) due to poor memory. Therefore, by scholarly and technical standards, this narration is weak in its chain.
