INDIANAPOLIS, Ind (July 30, 2014)– A single donor has donated $500,000 to the Suleman cause to help them achieve their goal of $1 million for charity.

Babar Suleman and his 17-year-old son Haris took off on a world-spanning journey to raise money for charity. They planned to spend 30 days flying to cities around the world including London and Istanbul.

The adventure was all for charity. The father-son duo aimed to raise money and awareness about Seeds of Learning, a part of The Citizens Foundation which sends poor children to schools all over the world.

“(This flight is) to promote not only the education of the underprivileged, but also to celebrate the fact that in the last 19 years The Citizens Foundation has been able to form 1,000 schools with 146,000 children,” Babar Suleman told FOX59 before leaving for the trip.

Their aircraft went down just after takeoff from Pago Pago in American Samoa on July 23. The crash happened about a mile away from the end of the runway and the plane went into the water.

Friends said crews recovered the body of Haris, who was going to be a senior at Plainfield High School. His father is still considered missing and crews have not yet found him.

Read the letter from the donor below:

I am an old high school friend of Babar’s and recently reconnected after several decades a few weeks ago, when he was briefly in Islamabad. I was of course shocked and saddened to hear about the loss of his son, and the doubts surrounding Babar’s own situation. I have instructed my bankers to transfer $500,000 to your charity to complete Babar’s goal of raising $1M. If you could please use these funds to honor his son’s memory and bravery by naming this gift in his (possibly their) name, I would greatly appreciate it!

The nonprofit’s response can be read below. The donor’s name has been removed per the donor’s request:

On behalf of all of us at Seeds of Learning, I want to personally thank you for your unbelievable generosity and kindness. When Babar and Haris Suleman undertook this ambitious mission to raise awareness of the dire need for quality education for children in Pakistan, they set an incredibly ambitious goal of raising $1,000,000. This money will enable Seeds of Learning-The Citizens Foundation to construct high quality schools for children in underprivileged areas whom without these schools would not have an opportunity for a successful future. Upon hearing the news of Haris and Babar’s crash, we in the local Indianapolis area were shocked and devastated. They played such an important role in our local community and it felt as our family had been ripped away from us. Babar and Haris had two legs left to complete their journey around the world. Thanks to your incredible gift, they will be able to complete their goal and vision of helping the impoverished children. It was an incredibly emotional moment when we heard of your gracious donation and the realization that their goal to raise $1,000,000 had been reached because of you.
