al-Hakam bin 'Utayba الحكم بن عتيبة · The Book of Salah

"O Messenger of Allah, tell me of a deed that will gain me admittance to Paradise." The Messenger of Allah (ﷺ) said: "Worship Allah and do not associate anything with Him, establish the Salah, pay the Zakah and uphold the ties of kinship. Let go!" - as if he was riding his camel. As if he was riding his camel and the man had grabbed hold of its reins to ask this question.

"I saw Sa'eed bin Jubari in Jam'. He stood and prayed Maghrib, three Rak'ahs, then he stood and prayed 'Isha', two Rak'ahs. Then he mentioned that Ibn 'Umar had done the same thing in that place, and he mentioned that the Messenger of Allah (ﷺ) has done the same thing in that place. Meaning Al-Muzdalifah.
