Throwing the pebbles of the three Days of Tashriq all in one day

Q: I read a Hadith by the Messenger of Allah (peace be upon him), reported by `Asim ibn `Ady that the Prophet (peace be upon him) allowed the camel shepherds to spend the night outside Mina throwing pebbles (at the pebble-throwing area during Hajj). Then, they throw pebbles the next day and the day after that for two days, then they throw pebbles on the Day of Nafr (departure from Mina, 12th or 13th of Dhul-Hijjah). (Related by the Five Compilers of Hadith [Imams Ahmad, Abu Dawud, Al-Tirmidhy, Al-Nasa'y and Ibn Majah], and ranked as a Sahih Hadith [authentic] by Al-Tirmidhy) I understood from this Hadith that those who have excuses are permitted to throw Jamarat-ul-`Aqabah (the closest pebble-throwing area to Makkah) separately. Then, they may throw the pebbles of the eleventh and twelfth days together on the same day, and finally they throw the pebbles of the thirteenth day if they are not in a hurry.I read a Fatwa by Your Eminence in a book entitled 'Fatawa Islamiyyah' (Islamic Fatwas), vol. 2, p. 284, under the title 'The Ruling on Throwing All of the Pebbles in One Day', as follows:"Q: Is it permissible for a pilgrim to throw the pebbles all in one day instead of throwing them during the three Days of Al-Tashriq (11th, 12th and 13th of Dhul-Hijjah), whether this day is the first day of the Days of Tashriq, the Day of Nahr (10th of Dhul-Hijjah) or the last day of Tashriq; then, they spend the night in Mina for two or three days without throwing pebbles, as they threw all of the pebbles in one day? Is this way of throwing correct, or should they throw the pebbles in the right order of days until they complete the throwing of the three days? I hope you will clarify this matter for us, along with giving (Part No. 10; Page No. 306) evidence."Your answer was: "Throwing the pebbles is one of the obligatory steps of Hajj, which should be performed on the day of the Festival and three Days of Tashriq for people who are not in a hurry, and it can be performed during the first two days for people who are in a hurry. This is performed each day in the afternoon, according to the action and saying of the Prophet (peace be upon him): Take your (Hajj) rituals from me. Throwing the pebbles cannot be performed before its due time, while it can be delayed in case of urgent need, such as over-crowdedness, based on an opinion maintained by some scholars. This is like the case of the shepherds when the Prophet (peace be upon him) allowed them to throw the pebbles of the two days on the second Day of Tashriq, 12th Dhul-Hijjah They should intend to throw the pebbles first on the day of the `Eid (Festival), and then throw the pebbles of the first, the second and the third days, for people who are not in a hurry. Then, they should perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah). Allah knows best." Issued by Shaykh Ibn Baz. I understand from the last paragraph of the Fatwa that it is permissible to throw the pebbles of the four days at one time along with intending to throw them in the right order. Is what I understand correct?This is supported by a Fatwa of the Permanent Committee in the same book entitled 'The way of throwing pebbles for people who delayed it until the last day of Tashriq because of illness or old age'. The Fatwa is as follows:"Q: If the pilgrims delayed throwing the pebbles to the last Day of Tashriq due to illness, old age or fear of over-crowdedness, may they throw Jamarat-ul-`Aqabah and the other pebbles at (Part No. 10; Page No. 307) one time, or should they throw the pebbles of each day separately, i.e. They throw the pebbles of the first day, then the second and the third, even if there is hardship in doing so?A: They should throw Jamarat-ul-`Aqabah first, then throw the pebbles of the eleventh day, then those of the twelfth and the thirteenth days, if they are not in a hurry. The Sunnah (action following the teachings of the Prophet) guides us to throw the pebbles of each day in its due date, depending on the ability of each person."By this answer, the Committee confirms the permissibility of throwing the pebbles of the four days all at one time.My question: I understand from the Fatwa of Your Eminence and that of the Permanent Committee that it is permissible to throw the pebbles of the four days at one time. However, this contradicts with what I understand from the above-mentioned explicit Sahih Hadith, if I understand well. The Messenger of Allah (peace be upon him) allowed the camel shepherds to throw the pebbles on the Day of Nahr, then they threw the pebbles the next day and the day after the next day for two days. Then, they threw the pebbles on the Day of Nafr. We hope you will clarify this matter for us. May Allah reward you with the best for the sake of the Muslims.
