Passage: Pargalı Ibrahim Pasha was a friend of Suleiman from before his accession. Ibrahim was originally a Christian from Parga (in Epirus), who was captured in a raid during the 1499–1503 Ottoman-Venetian War, and was given as a slave to Suleiman most likely in 1514. Suleiman made him the royal falconer, then promoted him to first officer of the Royal Bedchamber. Ibrahim Pasha rose to Grand Vizier in 1523 and commander-in-chief of all the armies. Suleiman also conferred upon Ibrahim Pasha the honor of beylerbey of Rumelia (first-ranking military governor-general), granting Ibrahim authority over all Ottoman territories in Europe, as well as command of troops residing within them in times of war. According to a 17th-century chronicler, Ibrahim had asked Suleiman not to promote him to such high positions, fearing for his safety; to which Suleiman replied that under his reign, no matter what the circumstance, Ibrahim would never be put to death.Yet Ibrahim eventually fell from grace with the Sultan. During his thirteen years as Grand Vizier, his rapid rise to power and vast accumulation of wealth had made Ibrahim many enemies at the Sultan's court. Reports had reached the Sultan of Ibrahim's impudence during a campaign against the Persian Safavid empire: in particular his adoption of the title serasker sultan (سرعسكر سلطان) was seen as a grave affront to Suleiman.Suleiman's suspicion of Ibrahim was worsened by a quarrel between the latter and the finance secretary (defterdar) Iskender Çelebi. The dispute ended in the disgrace of Çelebi on charges of intrigue, with Ibrahim convincing Suleiman to sentence the defterdar to death. Before his death however, Çelebi's last words were to accuse Ibrahim of conspiracy against the Sultan. These dying words convinced Suleiman of Ibrahim's disloyalty, and on 15 March 1536 Ibrahim was executed.

Question: What was the Defterdar's punishment?
sentence the defterdar to death
