Muhammad led a delegation consisting of two other ministers and two ministers to the event.
The Minister of Environment, Hajiya Amina Muhammad, stated this while speaking at the second year anniversary of the girls' abduction in Chibok.
The girls were abducted from their school dormitory by the Boko Haram sect on April 14, 2014.
Muhammad led a delegation consisting of two other ministers to the event.
"It is with heavy heart that we visit today. We visit today because it is not for want of efforts that your children,our children have not been found.
"We had prayed that we will bring good news to you now, but the only news that we are bringing to you is our continuous commitment to bring back those daughters to their families and their communities," she said.
Muhammad said that government would continue to liaise with the military and its allies in the international community towards finding the girls.
Other members of the delegation were Minister of state for National Planning, Hajiya Zainab Ahmed, her works, power and housing counterpart, Alhaji Baba Shehuri, Senator Muhammad Ndume (APC-Borno South) and Senator Binta Garba (APC-Adamawa North).
The ministers joined Governor Kashim Shettima of Borno to offer prayers for the safe return of the teenagers .
Some parents and relations of the abducted girls called for more effort for the release of their girls to relieve their pains.
Leader of the parents, Mr Yakubu Nkeki, in a speech, said the grief and sorrow of their missing daughters is boldly written on their faces.
"We cannot fathom your definite location and the condition you are in right now. Are you alive or dead? Are you pregnant, put to bed or empty?. Have you eaten the food of your choice or forced to eat something against your will? Have you taken your bath today? How do you take care of yourself during your menstrual flow?"
He said they are aware that nobody could answer some of the posers except the abductors of their daughters, urging the government to step up efforts at freeing the girls.
Borno State governor, Kashim Shettima said former President Goodluck Jonathan should be blamed for the woes of the Chibok parents.
He said the schoolgirls would have been freed few days after the abduction had the former president acted.
"The president didn't even believe the abduction took place. Perhaps that was why he and his wife never visited Chibok even for once."
He asked the people to submit the lists of indigenous contractors of Chibok extraction to the government for consideration for the award of contracts for the building of new schools and hospital in the townChibok.
