It should be considered that 49 pebbles are needed for three days (and if the pilgrim has to stay the thirteenth day then he/she needs 70 pebbles) that is better to collect them in the night of the Eid from Mash'ar and bring them in a bag with himself/herself, but it is better to have some more pebbles because it is possible that some of them may not strike the Jamarah. Article 273 It is an obligatory precaution not to collect the pebbles from mosques in there.
Article 274 Ramy al-Jamarah can be performed ride or afoot, with the right or the left hand, also there is no specific method for throwing them and having ablution is not a condition, although it is better to perform Ramy al-Jamarah afoot with ablution and with the right hand, and in that state it is better to praise and pray to Allah.
Article 275 Performing Ramy is not permitted in the night, except for women and ill persons and those who are afraid of the congestion of crowd in the day, or people who are busy in days managing and arranging the tasks of Hajjis in caravans (there is no difference in performing Ramy in the night before or after).
Article 276 Ramy al-Jamarah al-Aqaba and other Jamarat can be performed from any side, although it is famous that it is Mustahab to stand back to Qibla and facing Jamarah when performing Ramy al-Jamarah al-Aqaba, but it is Mustahab to face the Qibla in performing Ramy of other Jamarat.
Article 277 Whenever a pilgrim doubts about the number of pebbles which have been hurled, he/she should take the lesser number and perform the rest, and if he/she is sure about performing less than seven, he/she can perform the rest if the sequence has not been past and if it has been passed it is precaution to perform the rest and then perform it again by other seven pebbles.
Article 278 Whenever a person renounces Ramy al-Jamarah because of forgetfulness or ignorance about the matter, it is necessary to perform that whenever he/she remembers or informed about the matter until the thirteenth day, and it is better to perform the Ghazaa of the previous day before the noon and the duty of that day in afternoon; but it has no problem to perform them both in one time (first the Ghazaa of the previous day and then the duty of that same day).
