The Finance Director of PT GKBI Investment, Mr. H. Kusno Kasdi, SE, MBA, served as both the preacher and Imam for the Eid al-Adha 1446 H/2025 M mass prayer at Al Bayyinah Mosque in Setiabudi, South Jakarta. During his sermon, he conveyed several lessons from the story of Prophet Ibrahim:

• (1) Youth as a time for devotion as Prophet Ibrahim spent his youth preaching, maintaining strong faith, and benefiting his community. Young people today should follow his example.
• (2) The power of prayer and effort. Allah can easily grant the prayers of the faithful; our duty is simply to pray and make sincere efforts.
• (3) Obedience to God's will. Prophet Ibrahim demonstrated absolute obedience, even in unimaginable situations—fire not burning him, barren land producing Zamzam water, and his son Ismail being replaced by a ram before sacrifice. Every divine command carries wisdom and benefit.
• (4) Sacrifice as a sign of love and faith. Allah does not need the meat and blood of sacrificial animals; what He accepts is our faith and sincerity.
• (5) Prophet Ibrahim successfully guided his family to have unwavering faith, enabling them to carry out even the most challenging divine commands wholeheartedly.

The Al Bayyinah Foundation, which manages Al Bayyinah Mosque, is owned by the Federation of Indonesian Batik Cooperatives. According to the mosque's treasurer, Mr. Iwan Mulya Setiawan, SE, this year’s Eid al-Adha received the donation of 4 cows and 23 goats, with one cow contributed by PT GKBI Investment. The animal sacrifice took place on Saturday, June 7, 2025, starting at 8:00 AM and concluding after midday prayers. The meat was then distributed to residents across 17 RW around the Setiabudi district.
