As this wuquf is an act of worship for Almighty Allah (SwT)...
As this wuquf is an act of worship for Almighty Allah (SwT), it should be based on sincere niyyah without engaging in hypocrisy and show-off. Those having excuses, such as women, children, the ailing people, old men, the physically weak and those who need nurses and guides, can leave the Mashar al-Haram for Mina after some halt in the Mashar at night.
Chapter 4: Wajibat Of Mina (Obligations Of Mina) First: Ramy Of Jamarat al-Aqaba Ramy of Jamarat al-Aqaba refers to throwing pebbles at the symbolic Satans that are located in Mina. The pilgrim should use pebbles for ramy . These should not be very small such as gravel. Nor should they be very large. The pebbles should be of stone not of other material like clod, potsherd, and gems. However, different types of stones, even marble, can be used.
The pebbles should belong to the Mashar al-Haram, and those outside the Mashar are not acceptable. The pebbles must be new, that is to say they should not have been used for ramy in the past years. The pebbles must be mubah ; therefore, usurped pebbles or those procured by others for personal use are not sufficient. Ramy should be done from sunrise until sunset of the day of Eid al-Qurban . If the pilgrim forgets to perform the ramy on this day, he can carry it out until the 13th.
If he cannot carry it out by then, he should, based on necessary precaution, carry it out in person or through deputation. The following year, he or his naib should perform its qadha . Several things are obligatory in ramy : a. Niyyah , which should be sincere without hypocrisy or show-off, both of which invalidate the ramy . b. The pebbles should be thrown. Going close to the jamarah and placing the pebbles on it would not be sufficient. c. The pebbles, being thrown, should hit the jamarah. d.
Each ramy must be carried out using seven pebbles. e. The pebbles should be gradually and consecutively thrown. In this case, there would be no problem if they hit the jamarah at the same time. But all or a few of the pebbles should not be thrown at the same time, even if they consecutively rather than simultaneously hit the jamarah.
If the pilgrim throws a pebble but does not hit the jamarah, he should throw it anew, even though at the time of ramy he conceived that the pebbles had hit the jamarah. Therefore, if there are other things installed close to the jamarah and he has mistakenly thrown the pebbles at them, the ramy should be repeated, even if next year and by the pilgrim's naib .
