Ishaq bin 'Abdullah bin Abi Talha إسحاق بن عبد الله بن أبي طلحة · General Behavior (Kitab Al-Adab)

The Messenger of Allah (ﷺ) used to setup a pulpit in the mosque for Hassan who would stand on it and satirise those who spoke against the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) would say: The spirit of holiness (i.e. Gabriel) is with Hassan so long as he speaks in defence of the Messenger of Allah (ﷺ).

When the Messenger of Allah (ﷺ) saw the new moon, he turned away his face from it. Abu Dawud said: On this subject there is no tradition which has perfect chain and is sound.
