“One of the chiefs* sent me to Ibn ‘Abbas to ask him
about the prayer for rain. Ibn ‘Abbas said: ‘What kept him from
asking
me?’ He said: ‘The Messenger of Allah (ﷺ) went out
humbly, walking
with a humble and moderate gait, imploring, and he
performed two
Rak’ah as he used to pray for ‘Eid, but he did not
give a sermon like
this sermon of yours.’”
Sunan Ibn Majah Book 5, Hadith 464
