(2) باب وُجُوبِ الطَّهَارَةِ لِلصَّلاَةِ
It was narrated from Simak bin Harb, that Mus'ab bin Sa'd said:
'" 'Abdullah bin 'Umar came to visit Ibn 'Amir when he was sick and he said: 'Won't you supplicate to Allah for me, O Ibn 'Umar ?' He said: 'I heard the Messenger of Allah (ﷺ) say: "No Salat is accepted without Wudu' (purification), and no charity (is accepted) that comes from Ghulul [1] " and you were the governor of Al-Basrah.' "
