To throw pebbles on their behalf

Q: I performed the obligation of Hajj this year, 1400 A.H. I started the journey from my place of residence in Khamis Mishit and I entered the state of Ihram for Tamattu` Hajj (`Umrah during the months of Hajj followed by Hajj in the same year with a break in between) in which I was accompanied by another Muslim. After we arrived in Makkah and made Tawaf (circumambulation of the Ka`bah) and Sa`y (going between Safa and Marwah during Hajj), I lost sight of my friend who had all our money in his wallet, except for a small sum I kept with me. I went to Mina, `Arafah and from there to Muzdalifah. From Muzdalifah I went to stone the greater Jamrah. Afterwards, I performed Tawaf, Sa`y, shaved my hair ending my Ihram and then returned to Mina without slaughtering the Hady (sacrificial animal offered by pilgrims) or fasting. I depended on my lost friend ,who had my money, to slaughter the Hady on my behalf. Unfortunately, I could not find my friend until I returned to my hometown, Al-Khamis. There he informed me that he had not offered a sacrificial animal on my behalf. Until now I am at a loss and could not find anyone to advise me on what to do.On the first day of the days of Tashriq (11th, 12th and 13th of Dhul-Hijjah), namely on 11/12/1400 A.H., I stoned the Jamrah (pillars at which stones are thrown during Hajj) before noon out of my ignorance of the religious ruling in this regard. A person told me that I should repeat the stoning (at the stone pillars during Hajj) before sunrise of that same day, but the sun had already set before I arrived there. I did not perform the stoning, (Part No. 11; Page No. 294) as I believed that it was not permissible after sunset. On the second day of Tashriq, namely 21/12/1400 A.H., I stoned the Jamarat, except for one pebble because the seventh one fell out of my hands and I did not try to pick it up or even make up for it.
