History of Islam Vol 3 of 3 by Akbar Shah Najeebabadi

Abdur Rahman III 131
Following this,
the envoys of Italy, Germany, France and Sicily came to
the Caliph one after another to have good relations and friendship with
Cordova. Every ruler of Europe vied with each other to win the support
of Cordova to keep safe from their enemies.
Caliph Abdur Rahman made his son Hakam his heir apparent.
Another son Abdullah was inclined to religious practices and was
called "the pious". A Muslim jurist of Cordova tempted him to take
the throne by assassinating the Caliph. Abdullah in collaboration with
Abdul Bari, the jurist, hatched a plot to assassinate the Caliph and
the crown prince. Many others were made to join the conspiracy. But
the plot was unearthed on 10 Dhul Hijjah, 339 A.H. and both Abdur
Rahman and Hakam were saved. Abdullah and the jurist Abdul Bari
were put in jail. On the first day of their imprisonment, the Caliph
executed his son Abdullah and Abdul Bari committed suicide in the
prison.
On the death
of Ramiro the king of Galicia in 334 A.H., his son Ordono
succeeded him and sent his envoy to Cordova to seek permission for his
accession. The Caliph acceded to his petition and granted him
permission to rule in Galicia. In 345 A.H., Ferdinand the ruler of Castile
sent a petition recommended by Ordono IV to the Caliph to grant
permission for ruling and he was also given permission.
Sancho had occupied his ancestral State Leon and his maternal
grandmother Tota was the ruler of Navarre State. Sancho became
victim of fatness to such an extent that he was unable to even walk.
Ferdinand and Ordono dislodged him from Leon. Sancho came to his
grandmother in Navarre State where he also had a maternal uncle.
However, his grandmother ruled the State because of her abilities and
experience and played her role as the guardian of her son, Sancho's
maternal unde. Queen Tota sent precious presents to the Caliph and
entreated his help for the restoration of Leon and Galicia, which was
forcibly occupied by Ferdinand and Ordono and also to send a
physidan for treating fatness. The Caliph promptly responded to the
entreaty and sent at once a physician to Navarre. However, the
restoration of the lost State of Leon was put off to some other date.
Sancho responded to the treatment and was cured and he regained his
health and was able to be active again.
