Ruling on someone who stoned the jamaraat then when he came back to his country he realised that he had thrown fewer than seven pebbles
Question

                When my mother went for Hajj, she went to stone the Jamaraat, and she put some pebbles in her pocket and stoned the Jamaraat. Then she went back to the hotel and took off the abayah that she was wearing, and when she went back to Holland she found that some of the pebbles were still in the pocket of her abayah. Does she have to do anything as a result of this?
Praise be to Allah.
		There is no difference of opinion among the scholars 
		concerning the fact that the Prophet (blessings and peace of Allah be 
		upon him) stoned the jamaraat with seven pebbles (each). This was his 
		practice, beyond a doubt. 

	Ibn al-Qayyim (may Allah have mercy on him) said: 

	It is narrated in saheeh reports from the Messenger of Allah 
	(blessings and peace of Allah be upon him) that he stoned each Jamrah with 
	seven pebbles. This was reported by ‘Abdullah ibn ‘Abbaas, Jaabir ibn 
	‘Abdullah, and ‘Abdullah ibn ‘Umar. End quote. 

	Haashiyat Ibn al-Qayyim ‘ala Mukhtasar Sunan Abi Dawood 
	(5/31 2) 

	The scholars differed a great deal concerning the ruling on 
	one who falls short in the number of pebbles used in stoning the Jamaraat 
	during Hajj. There is no text concerning this matter to which reference may 
	be made in order to resolve the difference of opinion. 

	It says in al-Mawsoo‘ah al-Fiqhiyyah (17/80, 81): 

	The view of the Shaafa‘is and Hanbalis is that the one who 
	does not stone the Jamaraat at all, or omits to do so on one or two days, or 
	omits three pebbles in the stoning of any one Jamrah, must offer a 
	compensatory sacrifice. 

	According to the Shaafa‘is, if anyone is short of one pebble, 
	he must give one mudd in charity, and if he is short of two pebbles, he must 
	give double that amount. 

	According to the Hanbalis, there are several reports 
	concerning one who is short of one or two pebbles. 

	It says in al-Mughni: 
	                                    

	What appears to be the case is that Ahmad’s view is that he 
	does not have to do anything with regard to being short of one or two 
	pebbles. 

	The Hanafis are of the view that a compensatory sacrifice 
	must be offered if the pilgrim fails to stone all the Jamaraats on the four 
	days, or if he omits the stoning for an entire day. The same applies if 
	someone is short of most of the pebbles on one day, because it that case it 
	is as if he did not stone the Jamaraat at all, so a compensatory sacrifice 
	must be offered for that. 

	But if he omits a few pebbles on one day, then he must offer 
	charity, giving half a saa‘ of wheat, or  a saa‘ of dates or barley, for 
	each pebble he omitted. 

	The view of the Maalikis is that he must offer a compensatory 
	sacrifice for omitting a pebble or for omitting all of the pebbles. End 
	quote. 

	What appears to us to be the case – and Allah knows best – is 
	that if she is certain that she omitted three or more pebbles from one 
	Jamrah, then she must appoint someone to sacrifice a sheep on her behalf in 
	Makkah and distribute its meat to the poor of the Haram. If she is not 
	certain about that, then she does not have to do anything. 

	And Allah knows best.
