(47) باب الرُّخْصَةِ فِي تَرْكِ الْقِيَامِ
It was narrated that Ibn Sirin said:
"A funeral passed by Al-Hasan bin 'Ali and Ibn 'Abbas. Al-Hasan stood up but Ibn 'Abbas did not. Al-Hasan said to Ibn 'Abbas: 'Didn't the Messengr of Allah stand up for it?' Ibn 'Abbas said: 'He stood up for it then he sat."'
