1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following:

“I once asked abu ‘ Abd Allah , about a man who forgets throwing pebbles on al- Jamar until he is in Makkah. He (the Imam) said, ‘He must go back to throw pebbles with an interval of an hour between two throwing/ I then asked about if he misses it and leaves. He (the Imam) said, ‘He is not obligated for anything in this matter. 5 I asked him (the Imam) about the case of a person’s missing Sa‘y between al-Safa’ and al-Marwah. He (the Imam) said, ‘He must do it again.’ I then asked about if he misses it and leaves. He (the Imam) said, ‘He must come back and do Sa‘y between al- Safa’ and al-Marwah again, it is not like throwing pebbles on al-Jamar. Throwing pebbles on al-Jamar is sunnah and Sa‘y between al-Safa’ and al-Marwah is obligatory.’”
